Sims 4 missing mod folder

I have been playing sims 4 for some time now and i wish to add mods to it, however i find that every mod instructs people to put there files in the mod folder. However i cannot find such folder as it seems that i my game has installed in the origin's game folder and not in the Electronic arts folder (which is were everyone else's game seems to be) and thus the folders are completely different and in some cases missing like the mod folder.

How do i install the sims 4 in the electronic arts folder?  hope by doing so will fix my problem but i have tried to re-install the game several times and searched for an option to change it but i cant seem to find one...
