It's in the Sims 4 folder.
@EnochIsSalty And what folders are above Documents > Electronic Arts > The SIms 4? I suspect that you have your Documents folder inside OneDrive, but you need to look at the folders for that. You can also get the full path from inside the game: https://sims4.crinrict.com/eng/2018/07/how-to-find-your-user-folder/
If it's OneDrive, you actually need to get Sims 4 out of OneDrive. Syncing Sims 4 files with OneDrive results in things like OneDrive deciding to "fix" your folders by putting stuff you deleted back in, etc. We have support about Sims 4 OneDrive problems here: https://answers.ea.com/t5/Technical-Issues-PC/CURRENT-ISSUE-Sims-4-saves-user-content-disappearing-PC/td-p/12475370
