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

[stuarto]

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?

Not sure what might work in the MAC keyboard.

.....But did you try holding down the "fn" key and then hitting the f8 key??

That's the shortcut on Windows...might work on MAC too
