If you don't get any further comments in this user community forum from someone familiar with how TurboTax handles tax-exempt MA pensions on the MA state return, you can phone TurboTax Support tomorrow for realtime help during business hours.
When you right-click on that data box in the image that you provided above, is there any popup with an "about" link that provides any help/guidance for that screen? I know the Windows version often has such a popup for more info on various data screens; I don't know about Mac.
Also, since you have desktop software, if you go into Forms Mode and look at the state worksheets and forms, you might see how TurboTax is handling it on the actual worksheets/forms to see if they reflect the correct situation and conform to the state instructions dmertz provided the link for above.
Support hours are 5AM-5PM Pacific (8AM-8PM Eastern), Mon-Fri
You can use this contact form to get an incident number and phone number. Or it may schedule a call back.
