Due to the unusual situation this year your column A should reflect the correction as made by the IRS ... so this will take a bit of finagling ...

1) undo the amendment --- see instructions below

2) remove the form 8880 by going thru the interview and removing the retirement contribution trigger OR indicate you are a student in the 8880 input screen ... either will do.

3) review the return ... does the 1040 now reflect only the unemployment change ?

4) if so then close the program and log back in ... click on the amendment option 

5) reverse step 2 to put the credit back

6) review the 1040X ... is it now correct ? 

Column A should have the figures from the original return + the correction ,   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 + the corrected amount  you received.

Then you will see your extra refund on line 22 OR  the new balance due you need to pay on line 20.

How do I cancel or undo an amended return in the TurboTax CD/Download software?

If you started amending your federal return by accident and would like to cancel the amendment, follow this process to correctly "unamend" your federal return:

1. Open your return.
2. Switch to Forms Mode (Windows instructions | Mac instructions).
3. In the left pane, select Form 1040X.
   • Windows: After the form is generated in the right pane, click the Delete Form button at the bottom of the window.
   • Mac: From the Forms menu, select Remove Form 1040X.
4. Follow the on-screen instructions to remove the 1040X from your return
5. Important: Go back through the TurboTax interview and undo any changes you made after you selected the option to amend your 2018 return, as merely deleting the 1040X will not undo those manual entries for you.

State Amendments

The best way to "unamend" your state return is to go through your state return from the beginning and keep your eyes peeled for amend-related screens or questions.

The amend question usually appears right at the beginning or towards the end of the state interview (never in the middle).
