Why is a Form 1040-SR (Return for "Seniors" printing/

I'm doing my 2020 Tax Return and I was having problems completing the form.  I just noticed that it is a Form 1040-SR "US Tax Return for Seniors". I didn't fill out one of these last year.  It is very different from a regular 1040.  Why am I getting this "senior' form off the Turbo Tax Disc????
