When you do an amended return should it show you owe when originally you should have gotten a refund

First of all.....Do NOT amend  until the first return is fully processed and you get the first refund on the original return.   The Amended return assumes you already got the original refund.

Then The amended return will only show 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. If there is an amount owed with the amendment, it will be on line 20. When you go through the amendment section it asks you how much you paid or got back on the original return so be sure to enter it. You might need to go back and answer that question. I think it's one of the last questions in the amended section.
