@Jennifer T The child tax credit reported on Line 19 will be subtracted from the amount of taxes on your taxable income reported on Line 18. If the result is 0 or less only 0 will be reported on Line 22. The child tax credit is a non-refundable credit meaning once it has been used to reduce your taxes to 0 no further credit will be included as a tax refund.
However, if you are eligible you will receive an Additional Child Tax Credit reported on Line 28 of the Form 1040. This amount is will be included in the federal tax refund.
