@mayi0715 You clearly do have a Sims 3 user data folder, it's just not where you're looking. When you have iCloud enabled, there's a Documents folder locally on your computer, and a second one in cloud storage. Whichever one you're looking in now, try the other.
It's usually better not to have iCloud set to automatically sync Documents with cloud storage, as it complicates things for games that store their data in Documents. So please don't enable that feature. But you can get a better idea of how iCloud works and your options here:

The Electronic Arts folder and its contents are hidden from Finder searches.
I don't believe that's the issue. It doesn't appear as if I have iCloud enabled. Look:
Note: I have been doing extra searching, and I managed to find an "Electronic Arts" folder somewhere else
Desktop > The Sims 3 > The Sims 3 (Show Package contents) > Contents > Resources > translating > c-drive> Program Files > Electronic Arts.
However, this "Electronic Arts" folder doesn't have what I remember the one under Documents had.
@mayi0715 That's not the Electronic Arts folder you want; it's for the game's program files. Try searching in Terminal instead. Open Applications > Utilities, launch Terminal, and enter this:
find / -type d -name "*Electronic Arts*" 2>/dev/null
The command will take a while to run (let it go to completion), but in the end you'll get a long list of folders with the words "Electronic Arts" in the name. Please post the full file path of any that are specifically in Documents, as in, the file path contains Documents\Electronic Arts. You can write [username] instead of your username, but otherwise keep the file path intact.
Okay I really don't know if I did what you said correctly, but here's what the Terminal spit out:
/Users/User/Documents/Electronic Arts
/Applications/The Sims 3.localized/The Sims3.app/Contents/Resources/AddOns/The Sims 3 Ambitions.app/Contents/Resources/transgaming/c_drive/Program Files/Electronic Arts

I find it confusing that it says Electronic Arts after Documents because its definitely not there...
@mayi0715 Terminal is saying there's a Sims 3 folder in the Documents directory of the user just labeled User. Are you in that user account, or in a different one? Have you enabled sharing so that files get moved around between users or to the Shared folder?
You also somehow have a couple of Documents folders within the game's package contents, which is strange. You could go in and root out those folders manually—Terminal lists where to find them—but those are definitely not the folders where you'd need to add content. (If you do want to go looking, you nee to right-click and select Show Package Contents on any entry listed as [something].localized or .app.)
