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.
