Sorry, but as I said above the most you can qualify for (for everyone and for both the 1st & 2nd rounds) is only $900 total based on your 2020 AGI. You got 2900 for the first one. Which is 2,000 more than you qualify for. You don't have to pay the 2,000 back. So you entered 2900 in the first box? And entered a 0 (zero) in the second box? If you do not qualify for the Recovery Rebate Credit because of your 2020 tax situation then you will not be able to get the missed stimulus payment for the new baby.
Look at your return. The Stimulus payments do not show up anywhere as taxable income so you are not being taxed on it. And they are not being subtracted anywhere on your return either.
