"Unreal Engine C++ Dev"-#include path not defined, can't find <iostream -Help?

Hi, I didn’t put the file anywhere. When I closed VS Code the first time and re-opened it, one of the notifications said that I hadn’t defined my includepath so I clicked that and it opened the file, and I edited it there.

After that, I couldn’t even find the file again, so I did a global search on it, and I found it on my D: Drive, in the root directory, in a folder called “.vscode”. It is the ONLY file in that directory, which is weird.

Here is what is in the file and it is definitely the one I edited, as it contains that D path to my Visual Studio directory.
FILENAME: c_cpp_properties.json in D:.vscode
