How do I fix this? I received the advanced child tax credit . But it was supposed to go to her dad so I gave it to him since it affects his taxes this year

The fact that you received the advanced child tax credit (ACTC) means that you must report those payments on your tax return.  This could result in an amount that must be repaid to the IRS. The IRS letter 6419 will be issued to you so it's important to use this information on your tax return.  Since you gave the money to Dad, then he should reimburse you when his return is filed which will result in the full credit being given to him.  This would mean that he will receive the some of the money twice, the half you received and gave to him and the full amount of the credit ($3,000 per child or, if the child is under 6 years of age $3,600).

Fortunately, the IRS is offering repayment protection. This is an income-based program that forgives some or all of what you’d owe. We’ll check for this automatically if you're in this situation.

Repayment protection is an income-based program that reduces the amount of excess advance Child Tax Credit payments you have to repay.

Full repayment protection equals $2,000, multiplied by the following:

The number of qualifying children that the IRS took into account when estimating your advance Child Tax Credit payments, minus

The number of qualifying children you’re claiming on your 2021 tax return.

To be eligible for full repayment protection, your adjusted gross income (AGI) for the 2021 tax year must be at or below the following:

• $60,000 if you are married and filing a joint return or if filing as a qualifying widow or widower;
• $50,000 if you are filing as head of household; and
• $40,000 if you are a single filer or you are married and filing a separate return.
