FTUSA asks two questions which are leading to an incorrect entry on SCH HC line 4.
The first question asks if the health insurance is private, the second question asks if it's Health Connector. If you have health insurance thru MA Health Connector it's private insurance. You therefore end up with two boxes checked on line 4 (a and e) which is incorrect.
Stepping thru the official forms published by MADOR, the correct response for someone with MA Health Connector insurance is only line 4 (a) checked.
FTUSA needs to fix their S/W to align with MA DOR instructions.
