Maybe @IntuitBettyJo or @IntuitAustin could confirm that this is main reason, or even better get a detailed explanation of exactly what this box does to the return. 

My latest guess is that it is a signal that the return is being filed after 3/27 and things like ES dates are changed. Returns filed before now have hopefully been locked without this box being checked and printing them would show the earlier due dates. This would be only one of the affected items.
