Hi, all
I need some help to figure out how to handle this situation. My ex claimed our son on her 1040 form in 2020, now 2021 is my turn to claim my son as a dependant. But we didn't realize it and she didn't unenroll of the Advanced child tax credit program, now she received a mail stating X amount of money she received in 2020 as Advanced child tax credit.
My question is can I still claim my son as my dependant on this year's tax return to receive a full amount of child credit? and should my ex return the incorrectly collected child credit back to IRS? Would this cause any complications that could potentially prolong my tax return this year?
Thanks in advance!
