What a mess! The answer that I posted above worked for 2024. On further investigation, I see that TurboTax for 2025 flags any entry on Schedule 1 line 24z as an error. It essentially says that line 24z shouldn't be used at all, except for something called Domestic Production Activities Deduction (DPAD). Even worse, entering miscellaneous other income (which goes on Schedule 1 line 8z) doesn't work. The question-and-answer interview lets you make the entry, and it puts the negative amount on Schedule 1. But it does not put the description that you enter on Schedule 1. It just leaves the description blank.
I'm afraid I really don't know what to tell you at this point. Maybe there will be a software update in the next few weeks that fixes the miscellaneous income entry. Otherwise I'm at a loss.
