I am going to submit an amended tax return ( 1040X ) for tax year 2009. I forgot to claim the Making Work Pay tax credit ( schedule M ). Because of this mistake, I overpaid my federal income tax by $400. I'm filing the 1040X in order to get that $400 overpayment refunded to me. I find the revised 1040X form confusing. The 1040X chart instructions ( refundable credits section ) tells me to start at line 10. In other words, leave lines 1 thru 9 blank ? Does that sound right ? Also, do I enter the taxes that I paid with my original 1040 on line 15 ? The 1040X form indicates to do so but the instructions for line 15 don't make this clear.
Thanks much for any help.
