This may have been due to The Sims 4 folder not deleting automatically when you delete the install files for the game or Origin. You should be able to look here to find your saves. - C:\Users\Username\Documents\Electronic Arts\The Sims 4
If you still have your saved games in your Sims 4\saves folder - [C:\Users\Username\Documents\Electronic Arts\The Sims 4\saves] - It may be the game isn't reading the save files correctly.
Have you tried renaming your saved game file? To rename your save, remove the version number. - .ver0 or .ver1 by deleting the .ver1 on the end.
For example: Slot_00000002.save.ver1
Rename it to: Slot_00000002.save
You may want to give it a different number if you already have a save 2 in your folder. The game should then recognize the save file again.
-- If you have an old auto save file (Slot_00000001.save) it's safe to delete as the game doesn't use it anymore.
If the above doesn't help, Crinrict has some very useful tips on saved games disappearing:

When I've come across the problem of having a lot of saves in my folder and need to rename them is to move the saves folder to the desktop, and copy back only a few or so, maybe 10 at most at a time, and rename them in a 02.save, 03.save, 04.save, etc. up to 10.save
For example:
Slot_00000002.save
Slot_00000003.save
Slot_00000004.save
Load the game, select a save from the Load Game Menu and take notes of what save is what. To help keep track of the saves better.
