After you file

First you have to use the original refund amount to check on the original return here : 

https://www.irs.gov/refunds

 

Next do NOT file the amended return until the IRS has fully processed your original return and you have the refund in hand.  At that time you will have the funds to send back the excess refund you were not entitled to. 

 

Finally, send the payment with the amended return when you get to file it. And going forward do not file an incomplete return to start with ... the income section of the TT program had the unemployment section if you had looked for it  or asked how to find it before you filed the original return. 

 

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.
