Advance Child Tax Credit
I am helping a friend do taxes with Turbotax. He and his ex-wife take turns each year claiming their son. Last year (2021) she got an advance child tax credit as she claimed him for 2020 tax year. He is claiming his son for 2021 tax year and it asks if he received an advanced child tax credit. He did not but she did. How is this to be approached ? Should he answer yes as one of the parents did? Or should he answer no and what will this mean for her? They have a mutual agreement and always try to make things fair.
