...or...are you concerned about the 1040 vs the 1040-SR?

 

Those are the same form, just larger type flowing to 3 pages for the 1040-SR flavor, for those age 65 and older.

 

Desktop/Download users can turn off the 1040-SR form, and print just the plain 1040 (selection is on the "Info  Wks" when in Forms Mode.  But all the other attached forms and schedules are the same with either.

...Online  software users cannot choose.
