TouglasBoat If you're still dealing with this issue, you should be able to buy the packs from the EA website, for example here's Get to Work:
https://www.ea.com/en/games/the-sims/the-sims-4/buy/addon/the-sims-4-get-to-work
However, it's possible the entitlements from Steam will block you from using the new versions, in which case you'd need to unlink your Steam and EA accounts or have the Steam entitlements removed. So if you need to repurchase almost everything anyway, you might be better off creating a new account instead.
