Why do I need a 1040SR form with a VT state return?

TurboTax prints out a Federal Form 1040SR to go with the printed forms for mailing my Vermont State return.  I can't figure out if I really need this.  TurboTax has never done this before.  I have not had any reason to recompute my Federal return.  Any one have an answer?  Otherwise my faith in TurbTax is shaken.
