Deductions & credits

We received two months of Advanced Child Tax Credit payments before I was able to turn off the automatic payments.  With our increased income in 2021 compared to 2020, we no longer qualify for any child tax credit.  We received letters from the IRS with the amounts we received and the letters state that if we aren't eligible for the credit we need to file Schedule 8812 to determine if we must pay the money back.  How do we do that on Turbo Tax desktop version?  Thank you for your help.
