Do I put the total amount of my w2 if I worked in MA but lived in CT. Trying to answer the "Wages you earned outside of Massachusetts" question

If you worked in MA, your W-2 income is considered Massachusetts source income and it is taxable on your MA nonresident return. It is not considered wages earned outside Massachusetts. 

You can claim on your CT resident return, credit for taxes paid to another state to avoid double taxation. 

How do I file a nonresident state return?
