did you have gains or losses in 2023 or only a carry-forward ?
I'm guessing no gain/loss.
Did you attach Schedule D to your 1040-X?
IRS expected 1040-X Line 8 to show" SCH D ".
You can resubmit the amendment with explanation that Line 8 was wrong.
Amount paid Line 16 will depend on whether you send the $290 now or hold off for another IRS response.
