Why did I not receive the tax credit for my child that is 17 and a full time student in the amount of 4000.00 dollars?

The Child Tax Credit of $1,000 is only for a child that is under the age of 17 on the last day of the year.

You can still claim the child as a dependent on your tax return and receive the personal exemption for the child which is $4,050.  The personal exemption is Not a tax credit but a deduction on your tax return.
