@Meggiemooch560 The Mods folder is in Documents > Electronic Arts > The Sims 4 regardless of how you're launching the game. You do need to launch it once to create this folder though.
I have the same problem and i did everything like before but it did not show up in my game. But i play on a external hard drive. So how would i do that then?
@_Manou1996_ The Sims 4 user folder, the one that contains the Mods folder, is always in Documents > Electronic Arts no matter where you've installed the game's program files. If, however, you've used a symbolic link to move the user folder to the external drive, then that's where you need to look. This would have been a separate process, so if you don't think you went through that, you probably didn't.
Regardless, the easiest way to find your user folder is to use the in-game method described here:

Thank you soo much it was easy to find but needed help looking. Everything is working and showing up.
