Deductions & credits

Thanks for all of the info, the only thing im asking is if I normally would get a refund for my taxes based on the assumption that I have a child tax credit then if that tax credit has already been given to me, would I end up owing money for that same year.   Remember, I normally dont owe much in taxes thanks to my withholdings.  BUT this time I received $3000 back early on the advanced payments.   I received all my stimulus too so the IRS does not own me that.   So when I calculate my taxes for 2021 do I do that without having the benefit of the child tax credit I already received??
