My sims folder doesn't look right

@maybemayday  The key point here is that there are two Sims 4 folders.  One contains the game's program files: the game files themselves, as in, the data that the EA App installs and that is the same for everyone.  You can choose to install this data wherever you want, and it looks from your screenshot like that's what you've done.

The second Sims 4 folder contains user data—saves, saved households and builds, mods and custom content, etc.—and is always in Documents > Electronic Arts.  But the key here is that it's in the Documents directory for this Windows user.  The location of this folder is set by the operating system itself; you cannot simply create a new Documents folder and expect Sims 4, or any other application for that matter, to use it.

You can open this Documents directory by opening a File Explorer window and clicking Documents in the left panel, under Quick Access.  This folder has its own special icon rather than looking like a regular folder.  Once you open this folder, you'll see an Electronic Arts folder inside, and a "The Sims 4" folder inside that, with all your user data inside.

You can in fact move this folder elsewhere, and it's not overly difficult.  However, I'm not sure you're going to want to do this if you really don't know anything about computers.  In order for it to work, or at least in order to be able to troubleshoot any issue that arises, you'll need to understand how file paths work and how to move stuff around without losing it.  Plus, the user folder doesn't necessarily take up a lot of space.  Still, if you'd like help moving this folder, just ask.
