The amended return should have included the original tax due you paid. So the amended return should be only for the difference you get back.
Check the amended return line 16. Does it show the original tax due? That assumes you paid it. 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. 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. Pay the amount on the actual 1040X line 20.
