We cannot see your screen or your tax return so we do not know if you made a mistake. Sometimes it helps to delete the dependent in MY INFO and then enter them again---going very slowly though all of the questions.
Make sure you have entered your child as a dependent in My Info, and that you have entered the child's Social Security number. Careful— do not say that your child’s SSN is not valid for employment. If your child was born in 2025 make sure you said he lived with you the whole year. There is an oddly worded question that asks if the child paid over half their own support. Say NO to that question.
And....if your child turned 17 in 2025 you do not get the child tax credit, but you can get the non-refundable $500 credit for other dependents.
