Let's back up. If you filed and got accepted then added the 1099 INT you should have done an Amended return on a 1040X. I don't know if the 1040X is ready yet so you might not be able to efile it. In fact, You should not amend or change your return until you get the refund from the original return or your payment has cleared.
The amended return will only be the difference you get back or need to pay. You can confirm this by printing your amendment and looking at the 1040X. Line 18 should be your original refund amount and line 21 should be your additional refund. If you paid on your original return it will be on line 16 (but don't include any penalty on 1040 line 38). If there is an amount owed with the amendment, it will be on line 20.
Go by the actual 1040X. Line 18 should be your original refund amount and line 22 should be your additional refund. If you paid on your original return it will be on line 16. If there is an amount owed with the amendment, it will be on line 20.
Ignore the 1040V and the new 1040 . That is for the original return or what the original return would have been if it didn’t need correcting. Don’t pay the amount on the 1040V.
