CaseyScoggins Sorry for the late reply. Try looking on onedrive.com, both in My Files and the Recycle Bin. Look for files that start with Slot_ , as these would be saves, and check their dates to see if you still have any of your newer ones.
If you do find and restore newer files but they don't load in-game, please post a screenshot of the contents of the saves folder, as in, I'd like to see the file names and dates.
If you don't find any saves on onedrive.com, search your PC as well. Open a File Explorer window, click This PC in the left panel, and enter Slot_ in the search field in the upper-right corner. The search may take a while, but when it's done, you'll be able to see the dates and locations of any save files still present.
As for why this happened, OneDrive is enabled automatically in most cases, without the system really explaining what that means or the potential consequences. It sounds like OneDrive did sync some of your files from your previous computer. It also sounds like you may have let your computer overwrite some of your new files with older copies when you moved the Sims 4 folder. But hopefully at least some of the newer saves are still available, in the wrong location or named incorrectly.
If you're not sure what you're looking at, feel free to post screenshots.
