Working from home

I work for a business that is located in Mass but I live in New Hampshire. I have not been to the office all year and have worked from my home everyday. Mass taxes have been taken out of my paychecks all year because I did not realize not to have them taken out. I am filing a non -resident tax form so when it asks me how much was made in NH I would just list the total amount I believe, right ? So essentially I will be getting back everything I think.

Thank you
