I assume you mean they are NOT allowed to claim EIC, right?

First, double check that is the case (and see the link below).

If that truly is the case, is there a children involved that trigger the EIC?  If so, on the line where you enter the dependent's information, change the box for EIC to indicate the child is NOT a qualifying child for EIC.
