State tax filing

were you located in Mass at any time or did you solely work from a RI company?  Did you telecommute?  I'm a bit confused as to why Mass taxes were withheld when you said you worked in RI. What was in the state boxes for Mass from the employer?
Read rules of Mass for what is considered Mass income.
