Did you wait to amend until after the original return was processed and you got the first refund or paid a tax due? The IRS may have adjusted your original return.
Does your original amounts show up right on the amended return? You may have needed to change the amended return to include any changes the IRS made to the original return before making your changes.
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.
