Why can I NOT override the calendar year dates for Form10409/1040SR so that it reflects a fiscal year that begins July 1 20xx and ends June 30 20xx?
The option to change shows at the top of the Form 1040/1040SR but the override option to allow me to change the default January 1 to December 31 is greyed out and can't be used.
WHY?
How do I get this to work?
