TurboTax asked about the first stimulus check for those who did not receive full checks. The recovery rebate is only applying to the first check. What about the second?

The program asked for the exact amount of the first check but not the second. I had a child born in 2020 so I missed out on her stimulus checks. Therefore, it is only applying a rebate amount of $500 from the first round for dependents and not the $600 for the second check.
