Where does a Massachusetts Self Filer sign the State Return? There's only an area for "Paid Preparer" on Form 1, nothing for "Self Prepared" or "Sign Here".

I just finished my taxes using Turbotax Premier 2017. I've used TurboTax for about 20 years without problem. I live in Massachusetts. I printed out my state return, reviewed it, all OK, went to sign, and there is no area designated for a "Self Preparer" to sign. On "2017 Form 1, pg 4", which is where it should be, there is an area for a "Paid Preparer" signature and information, but nothing for a "Self Preparer" or "Sign Here".  Oversight?  Any required protocol besides just signing anywhere at the bottom of that page along with my ssn, date and spouses information? Thanks.
