@jenipenimmx When you sign into Origin or the EA App, do your packs show as owned? If not, you may be in the wrong account, as in, not the one that purchased the packs. Please check any other email addresses you have for receipts or other email from EA, or just input the address in the sign-in window and click "Forgot your password?" If the address is attached to an account, you'll receive a password recovery email.
Please also let me know whether you have one or two Sims 4 icons in your game library.
If you bought your packs from Origin, Steam wouldn't know anything about that, which is why it's prompting you to buy the packs again.
