First ... do NOT amend the return before you have received the original
Then ignore the Refund-O-Meter and look at only the form 1040X …
Column A should have the figures from the original return, Column C the
corrected figures and Column B the differences between the other 2 which needs
an explanation on page 2 of the form 1040X.
If you completed it correctly you will see an entry on either line 16 OR 18:
On line 16 should be the amount you paid with your original
On line 18 should be the amount of your original refund you
Then you will see your extra refund on line 22 OR the new balance due you
need to pay on line 20.
