The addition of the 1099-R can affect many other things on the return ... compare the original return line for line against the corrected one to see what happened. Several things that could have been affected are your taxable SS benefits, adjustments on the 1040, Sch A deductions and credits (both refundable and non refundable).
Switch to the FORMS mode to see the corrected 1040 and the 1040X.
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. If you paid nothing already then this line should be zero.
On line 18 should be the amount of your original refund you received. If you have not received your refund yet then you need to wait for it. If the refund changes from what you expected then this line must reflect that change.
Then you will see your extra refund on line 22 OR the new balance due you need to pay on line 20.
