You said; Regarding your original omission, as far as I know, there is no user-selectable option to not apply a capital loss carryforward. So, how did this omission of my capital loss carryforward happen?
I sent the Schedule D as part of my 1040X with the correct cap loss figures! My 1040X Amendment had the Schedule D with the correct cap loss carryover figures for 2023. And my AGI was accurate. With the doubled interest amount removed that lowered the AGI by $2,054, and it was lowered by $3,005 using $3k of my cap loss plus $5 for CIL. The AGI was correct on Line 1 Column C.
So, I don't see why I would need to file a 1040X No.2 There would be no change from 1040X No.1
