This does not work. When I go to EDIT menu, there is only an option to 'Mark as Estimated' . When this (or F8) is selected, the entry turns from dark blue type font to red italic. At that point "Mark as Unestimated" is an option. Pressing that, the line entry returns to dark blue... but attempting to file return delivers same error statement. And "Mark as Unestimated" is not an option....
