@guamcvey Understand. Have you also deleted the dependent and re-entered them?
If the child is under the age of 17, lived in your home for over 6 months. did NOT provide over one-half of their own support, the check box for Not Valid for Employment was NOT checked in the Social Security number section, that you indicated that no one else in household provided support for the child, then they would be eligible for the child tax credit.
There is no glitch in the software, this dependent section has been completed millions of times without issue.
