Where do you attach the W2 and 1099 form on Form 1 for MA?

Where do you attach the W2 and 1099 form on Form 1 for MA? I don't see a spot to attach the paper W2 on the form or the 1099 form to amend the state tax, Form 1, for MA.  The instructions say to attach the state copy of the W2 form and any 1099 form though. Could I just attach them to the front or to the back of the taxes?  Where should I staple them?

Thanks so much for your help and time! I appreciate it!

Staple them to the front of page 1 of Form 1.

According to Mass.gov website under Tips for Filling Massachusetts Personal Income Taxes it says  "Please do not attach checks or other documents to your return with staples or paper clips. It will definitely slow down the processing of your return."

Turbo Tax's answer is incorrect.
