After you file

Yes----if that box for child tax credit is not checked then you made a mistake somewhere.   You will have to be very careful when you amend.  You must enter the children's dates of birth correctly, enter their Social Security numbers----and make sure you do NOT say their SSN's say "not valid for employment".    When it asks if they paid for over half their own support say NO.   Be careful when you answer how long they lived with you in 2021.   It has be for at LEAST half the year.   The first choice in the menu is "whole year."   If your child was born in 2021 choose WHOLE YEAR.
