@supersure --
Assuming that you never physically worked within MA, @MayaD 's original answer is correct.
You must file a non-resident MA tax return on which you show the MA withholding and on which you claim zero MA income. This will result in your receiving a full refund from MA.
Your income, including your earnings from MA, is 100% taxable by your home state of RI.
MA does not tax non-resident remote workers who never physically work within MA.
