Maryland EIC issue

[lyndaj0331]

I have a client that is eligible for EIC with no children.  She does, however, list her parent as a dependent.  The Maryland return is picking up the parent as a child and is being rejected "Line 42 REfundable Earned Income Credit - For Taxpayers with Qualifying child must be equal to state EIC from Line 22 multiplied by .90 minus Maryland tax from Line 21 of Form 502."  The entries are correct on the dependent - Parent, DOB is entered; on 502B the box for 65 and over is checked.  I have updated and re-run review.  Any suggestions?

Thank you
