After you file

Ok ... let's see if I have this correct ... you paid a nanny thru a service that paid the Sch H taxes to the IRS for you AND issued the W-2 to the nanny and filed the 941/944/W-3 forms as needed for you.   You were NOT supposed to file a Sch H on the return in addition to what  you paid thru the service. 

 

Those payments  are not estimated payments to be entered on the income tax return.  So if you did put it on the return the IRS denied the payment.  

 

SO ... if you did file the sch H on the return incorrectly  then simply amend the return to remove the taxes you should not be paying on the return to get the refund of the taxes you should not be paying.
