I am having problem completing 2010 1040x I forgot to include a 1099 and will now have to pay part of my refund back (sample original refund $500 s/b $400), Do I put the original refund that I am to receive from IRS on 1040x line 14? I will pay IRS before due date the $100.00 to avoid late payment/interest, I am aware that I should not file 1040x until I do receive the refund check.

The origial refund should be shown on line 17 of the 1040X - "Overpayment as shown on original return.'
