Rejection SEIC-F1040-506-01: On Schedule EIC, the qualifying child's social security number (Line 2) cannot be used more than once in a tax return or on another return
This rejection occurs when you try to claim the Earned Income Credit (EIC) for a child on your return, but that child has already been claimed for the EIC on another return.
Usually the custodial parent gets to claim the EIC, even if the noncustodial parent gets to claim the dependent exemption and Child Tax Credit per divorce decree or other agreement.
