Deductions & credits

to be more clear, I am only interested in the child tax credit at this time.  I don't have any questions regarding the  EIC, except that Schedule EIC was in the list of "Forms", but the individual doesn't qualify for the EIC, so I wondered if the form was there as an idle calculation or if it is required to prove "qualifying children" for other credits.   It's hard to be clear under pressure and deadlines.  Thanks again.
