19 taxes I claimed 3 dependent children, 2 I claim every other year. I got stimulus for the 3 and me both times. But I had a baby in 2020 how do I get stimulus for her?

In turbo tax if I enter the amount I received for the Myself and 3 dependents. It doesn't let me get the stimulus for the baby. Since 2 of the children have been removed as dependents this year.

You are correct.  The calculations are correct.  The Recovery Rebate Credit is based on the information in your 2020 tax return.  The stimulus payments received in rounds one and/or two were advances on that credit.  At the time of stimulus rounds one and two, a 2020 tax return was not available so prior year return information was used.  

On your tax return you would be eligible for you and 2 dependents.  That would be 1200 plus 1000 (round one) and then 1800 (round two) for a total of $4000. That amount would be reduced by the stimulus payments you actually received in rounds one and/or two (2700 and 2400 totaling $5100).  There would be no credit left to add to your tax return.
