I don't understand why my child tax credit is only for one of my children when I have three that qualify.

The Child Tax Credit, available only for a child 16 or under at the end of the tax year, is a non-refundable credit that can be used only to offset tax. You get only enough child tax credit to reduce your tax to zero, up to a maximum of $1,000 per child. If your other deductions and credits have reduced your tax to zero when the child tax credit is calculated, you do not get any child tax credit.
