I got it fixed.
The solution is to open the 1040 form manually and then change the number on the Line(s) that was (were) wrong. In my case, my Line 18 was wrong and I changed the number, which is the Refund I just got from IRS. Because I missed reporting a $605 on my filed return, now my 1040-X said I owed $145. This $145 matches the different between my original filing's refund and the amended filing's refund ( assuming you ran the software with the accurate data).
