amending tax return to add recovery rebate credits

Hi I've perused around for a while and didn't see anyone that seemed to be in my particular situation so ill start a question thread. I'm amending my 2020 return to add a W2 and change my filing status to no one claimed me as a dependent because it was a mistake. While doing this I realized I qualify for all 3 stimulus checks since I wasn't a dependent in 2020. But all the Q&A forums for TurboTax seem to only show me how to get rebate credits when filing. Long story short, how would I file for my recovery rebate credits (I think all 3 would be around 3.4-3.6 K) when amending my tax return. Thanks in advance for any help!
