I lived in Massachusetts for 6 months in 2019. As such, I am only required to show health insurance on the Mass state return for the dates of residency. When I go to the screen where I am asked to check off the months I had health insurance while a resident, all 12 months are already checked off and I cannot uncheck the months I was not a resident. As a result, the software is calculating a penalty on my return for not having full year coverage. Is this a software glitch that has not yet been discovered. Has anyone else encountered this?
