You almost certainly aren't required to file a MA return, so you can remove it from your tax file.

From MA DOR website: Nonresidents are required to file income tax returns with Massachusetts if their Massachusetts gross income (derived from sources within Massachusetts) exceeds either $8,000 or the prorated personal exemption to which they are entitled, whichever is less.

If you are not sure, here is the formula for the prorated personal exemption.

The prorated personal exemption: (PE) formula:

PE per filing status ($4400 if single)    x    Massachusetts gross income (from sources within MA)   =    Prorated PE
                                                                        Massachusetts gross income from all sources
