I had custody of my grand niece the last couple of years, she moved out and back with her dad on May 12, of this year. I don't know how or who I report it to. I need to not claim her for the 2021 taxes. And also when I went to search in TurboTax, I think I clicked the wrong button, it said married or new dependent, but it neither of those and I need to change that.
