All I can say is the check box is on Form 1040 WAY OVER to the right of his name.
also, what is more important than remembering what your received (and I appreciate you are not in from of your compute currently) is that you ENTERED exactly what was received.
Even though your child was born in 2020 and one would presume that Line 30 should have $1100 listed, I can think of scenarios where that would not be tru
1) your income is too high to provide you with additional stimulus
2) that box is not checked. I've seen other posts where that is true. Be sure you answered the question about how long you child lived with you in 2020 as "ALL YEAR" as there is a note on the screen indicating to answer that way for 2020 new borns; if you answered 3 months - that is the problem. Otherwise, delete the child from your return and re-enter. You need to see that checkmark under 'CTC' for Line 30 to work correctly
let us know what happens.
