Basically the child
that you claimed for child care cost was already claimed by someone else
on their tax return.
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
