Didn't receive first or second stimulus check for child born in 2019

I just received my second round stimulus check and for the second time my child didn't receive a payment. We filed our taxes for 2019 in February 2020.  And qualify for the full amount. 

 

I see for out first missed $500 child payment we can use a recovery rebate credit: https://blog.turbotax.intuit.com/tax-deductions-and-credits-2/what-is-a-recovery-rebate-tax-credit-4...

 

What about for the second round? The second round is passed as a 2021 act, but I believe based on 2019 taxes again. Would we be able to file the missing $500 AND $600 payment on our 2020 taxes? 

 

I know it's early and day one, but wanted to ask right away to see how others will be handling this issue. Thank you.
