Entering the DOD as xx/xx/2023 just notifies the IRS of it.  

It doesn't indicate 'final'.... as a matter of fact, there's no place on the F 1040 to mark 'final' like there is on entity returns. 

The need to file a return is determined year by year, depending on income levels.  As my collections are so far down this year, and since I may just up & quit.... I might not even have to file a return for 2023 😉
