That's the problem, it doesn't reset to zero when I start.
When I'm finished with my changes, the expected refund still includes this additional amount that I already received in the original refund.
Original Schedule 3 of form 1040 has the following (just to illustrate, not my actual amounts):
1. Foreign tax credits: 456
6c. (form 8911): 78
7. Add Lines 1 to 6: 534
Line 13b on the original form 1040 also shows 534
When I start the amended return, before any changes, it immediately shows I'm due a refund of 78.
Line 7 of form 1040-X shows:
A - Original Amount: 456
B - Net Change: 78
C - Correct Amount: 534
I believe that Original Amount on Line 7 of 1040-X should match Line 13b on original 1040, but in this case it doesn't.
