On Child Care Expenses page, it already reads I have $5,200. employee provided care benefits. Why? My W2 reflects the actual, $2,600., in Box 10. Why the discrepancy?

somehow you entered the same amount twice.  did you enter your w-2 twice 

Thank you. That's exactly what I did. I had jumped ahead to forms and had entered some information manually prior to following the step-by-step format so, when I entered Box 10 of my W2, it doubled it up. I appreciate your help and intervention.
