This rejection code pertains to the Form 2441, Child Care Expenses. This return has been rejected by the IRS, because one or more qualifying persons identified on Form 2441 Part II, Line 2(b) have already been claimed as a qualifying person on another taxpayer's return.
You will need to contact the IRS directly and paper file your return only if you are going to still claim these expenses for this child. Otherwise your other option is to remove the Form 2441 child care expenses.
