Hi! I followed the tutorial, but feel like i did something a little bit earlier. The issue on the corner cannot be fixed in edit mode, mirror option is also was applied. Is there any chance to fix it?

Almost inevitably with this common point students come up against it, is double geometry.
Rather hard to see what you expected and what is wrong, but before moving anything, try selecting all with A and Pressing M, By Distance.
General Q&A note
Help us all to help you.
Please give FULL screenshots with any questions. With the relevant panels open.
Also, include the lecture time and name/number that is relevant to the problem/issue.
The screenshot can be done by Blender itself, via the âWindowâ menu bar top left hand side.
On that menu drop down is âsave screenshotâ.
Close ups additionally where they help.

Good idea, must admit I do not use that quick \Fav at all. Never got into the habit.

Hi! Thank you for the answer and Q&A advice!
I did what you said before, but it didnt help me

Because you mentioned that you applied your mirror, my best guess is that your second screenshot is showing the opposite corner, what itâs supposed to look like, and your first screenshot is showing your issue.
Something isnât right about thisâŚ
These orange edges are angled downwards in this first screenshot, but in the second one, theyâre level. More interesting than that, the green edge seems to be in the same position and angle in both screenshots; however, in the second screenshot, it lines up with the vertex at the red X, but it clearly doesnât do this in the first screenshot.
I have a funny feeling you have duplicate faces there; even though you might not see any z-fighting, that doesnât mean they arenât there. Duplicate vertices donât get deleted by merge-by-distance if you use the default distance of 0.0001m and youâve moved the duplicate vertex from its âpartnerâ in some way, thinking there was only one vertex there to begin with, and it looks like thatâs what happened here (otherwise the green edge would not exist and blender would render this area as a non-planar N-gon). I think thatâs the only reason why merge-by-distance didnât fix your issue. I struggled with the same thing when doing these pillars because I didnât understand that RMB is not enough to cancel an extrusion - that only cancels the transform of the extrusion. It has to be followed up with Ctrl + Z to cancel the extrusion itself.
If you turn on X-ray mode with Alt + Z, you should be able to trace along your edges and see where you can edge-slide one vertex onto another to fix the problem. Once thatâs done, perform a merge-by-distance as described by @NP5, and that will get rid of your duplicate faces.

hi! Thank you for reply! Before i just created a new pillar, and that one i hide as Broken pillar :D.
I just checked in X-ray, there are no hidden verticles, faces, vertexes or anything like that I hope once i`ll find a reason oh this fail.Thanks for the help!

Cheers =)
Iâm glad it didnât keep you stuck; good for you for carrying on and continuing to get better! In the name of trying to learn what happened, thereâs one other thing you could try to be absolutely certain there arenât any duplicates.
In the Viewportâs Overlays dropdown, you can toggle Statistics to see a count of faces, edges, and vertices, among other things. The first number is what you have selected, and the second is a total.
Because this is a low-poly model, itâs easy to count the number of vertices in this small corner by hand. In X-ray mode, if you box-select vertices around that area (and youâre careful not to select anything from behind), the first number in the Vertices part of the statistics should match what you counted by hand.
If that doesnât turn up anything unexpected, locally merging-by-distance with an increased distance (just drag the slider around and see what happens) doesnât work, and you donât accidentally have another pillar rendering exactly on top of this one, then Iâm all out of ideas and itâs a lemon, lol! XD
I guess if you really wanted to, you could delete the head of the pillar and rebuild it from scratch for some manual geometry-building practice (thatâs how I fixed mine when stuff happened). Not the best workflow of course, but on a nice square model like this, it should be pretty straightforward to do that evenly, even without the mirror modifier.
Have fun with the course!

If you can upload the file somewhere we can get it, then that will let us have a closer look.

Hi! There is no need anymore,at least for now 
i just deleted the top and made it again! I think sometimes its better to remade it again, instead trying to fix it myself with my poor knowledges
