Are you asking about the child tax credit on your 2020 tax return---or the advance monthly payments for 2021?
The law for 2020 says that you get the CTC on your 2020 tax return for a child who is YOUNGER than 17 at the end of 2020.
For the new 2021 child tax credit the child has to be YOUNGER than 18 at the end of 2021.
