Packs, Stuff, Kits, and more

Hello and Goodday!

I recently just got a pc and was interested in playing Sims 4 with all my packs and event rewards. Not sure if it's something i did wrong or not, but i've purchased almost everything in terms of expansion packs, stuff kits, and i've participated in live events. Sadly, none of the things i have, transferred over to my computer. I played playstation/console all the way up until this point and have no idea how to go about recovering my add-ons. I logged into my EA account through the playstation portal thinking i could be able to download all my stuff easily that way, but it all reflects that i haven't purchased it yet. Also, i have an xbox and none of the content transferred over to that console either. Please let me know how i can rectify this and thank you in advance for your help with this!😁
