In your Massachusetts return, you will reach the page that
says: Let's Go Over Your Health
Insurance Information. This will bring you to the area where
you will enter the information from your 1099-HC.
Note: If you have private insurance, a Masshealth Plan, a
Commonwealth Care or a ConnectorCare Plan, most of what is needed for this
section of your state return comes from Form 1099-HC, sent by your
insurance provider. (If you have government subsidized insurance, you won't
always get a 1099-HC.)
