Child status to claim child tax credit
My wife and I have cared for our Grandson (has lived in our home) for more than six months in 2020. We have paid for over 90% of his daily needs while his mother, our daughter, is away at college. His mother claimed him as a dependent on her 2020 taxes. Can we still claim the Child Tax Credit for the time we have cared for him without him listed as a dependent on our taxes? If not, is there another credit or deduction we may use? Thank you.
