How do i pay back advance child tax credit if i don't qualify for repayment protection?

[Linda20]

Divorced parents take turns claiming child and I received advance child tax credit but am not claiming child for 2021.

How do I "pay it back" on the 2021 return?

Answer the question concerning how much you received in 2021 as  ACTC, the program will notice that no qualified child is claimed and it will add the amount of the ACTC to other taxes.

Repay depends on income level right?

The income level forgiveness is on the worksheet

Correct, repay depends on income.   It's possible to have received ACTC for a child you cannot claim in 2021 but not have to pay it back.
