Are you absolutely positive about this? I have this for Grayscale Bitcoin Trust. Mine is also shown as a negative number. It appears that it would be entered inside TurboTax in the Investment Expenses screen, after the Investment Interest Expense (Margin Interest) screen. When entered there, it populates in the 4952 Worksheet and has a tax impact. Are you saying it should not be entered here?
It appears to be applicable based on the info under Learn More.
