How old is your child? The child has to be under 17 on Dec 31 to qualify. Go back and check the birthdate under Personal Info. Also make sure you have entered their ssn.
The Child Tax Credit is not a "refundable credit". This means that it cannot be used to reduce your tax liability below zero. Your Federal income tax withheld is not included in the calculation of your tax liability. In other words you have to have a tax to reduce. If your income is low and you don't owe any tax you won't get any credit back. Or if you only owe a small tax then that's all you can get back.
OR there are a couple questions you could have answered wrong under My Info. If your child was away at college, count the number of months away as having lived with you. The correct answer to claim the person is to say “the whole year”. This will indicate you supported the person the whole year, thus it will be entered on your return correctly showing up as a dependent.
Or the one that says did your CHILD pay more than half of their support. It’s not asking if you did.
And I think you have to have $2,500 of earned income to get the Child Tax Credit.
