How do I handle the Child Tax Credit advancement if I want to file separately for 2021 but filed married jointly in 2020? The 2 kid $3,000 direct deposit advancement all went to my separated spouse's account. I see from limited research that my name is attached to half of that, $1500. So when I run my simple return numbers, I go from a $450 return to owing like $1,000 because of that.
