State tax filing

I have the similar issue.  Mom had Roth IRA.  It was started before 2015 and She was 90 years old when she died in November 2018.  I inherited the Roth IRA in 2019. I am 70 years old. I’m not being taxed Fedrally, but even if I check the Qualified box in TT, Mass still seems to be taxing me on this distribution.
