@Anonymous I can't tell exactly what's going on here. The brokerage statement that you posted shows a net gain of $3,318, but there's something included in the totals on Schedule D line 1a that's not in the totals on that brokerage statement. And you didn't show the rest of Schedule D, so it's not clear what your overall loss was. I don't want to get involved in analyzing your whole tax return, but if $49,714 is the overall net loss that you reported, and $42,522 of that will be disallowed, you would still have a net loss of $7,192 on your tax return. If that's the case, you would not be paying any additional tax for 2020. Only the carryover to 2021 would change, which is what you said in your first post. In a year or two you will pay more tax than you otherwise would have, because your capital loss carryover will be less, but you wouldn't have a payment due with your amended return.
