The additional payment is probably interest paid by the IRS for a late tax refund.

The IRS has been processing returns in 2 parts ... the original refund plus any interest  and any refund for the unemployment exclusion you are entitled to later.  

So I should expect another amount for the tax I paid on unemployment since I fall in the guidelines that is set?

Yes that is what is being reported ...  but do you know if you will be getting anything more?   Not everyone does.

First save a PDF & .taxfile  of the original return for safe keeping ... then use the amendment option to recalculate the return to see the new bottom line  but do NOT file it.

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.

Does the IRS let you know that you will be receiving the tax on a date like they do with the returns? I know I am entitled to getting my taxes back I paid on unemployment. I just don't know for sure when that will be coming and the total amount. Turbo never showed me either.
