@mggundy16 When you moved the Sims 3 folders to the desktop, you prevented the game from reading their contents. You can restore the saves and anything else you'd like to keep, but first, it would be best to deal with the OneDrive issue. Is the new Sims 3 folder in OneDrive's version of Documents?

The guide was written for Sims 4, but the OneDrive part applies here too.
Make sure the game is reading the location you want going forward. Right-click the new Sims 3 folder that gets created, select Properties > General, and look at the Location. It should be this:
C:\Users\your username\Documents\Electronic Arts\The Sims 3
You can move your saves to the Saves folder inside, and drop your Mods folder in there too, plus anything else you'd like to keep. Here's a description of the files in that folder:
