@MamusiaTheCat When you install the base game through Steam, Origin installs your packs into the same place as all the Steam data. If you haven't changed the default install location in Steam, this is where the content would be:
Program Files (x86)\Steam\steamapps\common\The Sims 4
Each pack has its own folder inside that Sims 4 folder, and they're named by type of pack and release order. (For example, Snowy Escape was the tenth expansion released, so its folder is EP10.) It should therefore be easy to see whether Origin has downloaded all your packs.
It's not possible to add your Origin-bought packs to your Steam library.
Thank you for explaining! I did manage to find that Origin downloaded my DLCs to where Steam usually installs games a little while before your comment but I am still thankful for detailed answer. Also, where do you recommend getting my future DLCs? I really prefer sticking to one platform but it's kinda hard to do. Most of DLCs I own are on Origin (Seasons, Get Famous, Laundry Day Game Pack, Holiday Celebration Pack). I also own Cats & Dogs from Steam -34% offer for getting the game with that DLC and the following which I am not sure whether to count as actual DLCs of any sort: Awesome Animal Hats, Life of the Party, Up All Night
