Print only the forms needed using the PDF reader to choose them only ... so know what changed you need to compare the original return against the amended one ... any form or schedule that changed needs to be sent. Use column B of the 1040X to hone in on what changed ... any entries on that column needs to be supported.
Look at 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 return.
On line 18 should be the amount of your original refund you received.
Then you will see your extra refund on line 22 OR the new balance due you need to pay on line 20.
