Supporting Details in Mac Desktop -- cannot mark a line item as ESTIMATED

I switched to using Mac Desktop from Windows this year (Turbotax 2024). One frustration I have is that when I use a Supporting Details sheet for any form entry, I cannot mark a line item entry as ESTIMATED the way I used to be able to do on Windows, (nor can I mark the resulting form field as Estimated). The Edit Menu Item for "Mark Estimated" is greyed-out when working in the Supporting Details sheet.

This is a big step backward in my view. Has this changed for 2025 or is it a bug just on Mac? Any workarounds?
