First, it's your responsibility to
determine whether your insurance meets Massachusetts MCC requirements.
See here for more info:
As you are covered by your mother's insurance, complete the Massachusetts Health Insurance interview as
follows:
Enter the insurance company name and the subscriber
number (your mother's, if you don't have your own subscriber/member number), but leave the FID blank. When asked if you received a 1099-HC,
answer "No". You may see an error during the state review, which you can
ignore.
