Note that when using turbotax, you must manually allocate your income, the program can't guess for you. Also, MA can only tax "MA-source income". That includes income you earn from working while physically located in the state, and can also include lottery prizes or income from MA real estate (selling or renting). MA source income does not include investment income (interest, dividends, capital gains), lottery prizes from other states, or a side gig that is not performed in MA, even if you work in MA part of the year. So be careful when allocating your income, MA may get 40% of your wages but they get 0% of your investment income if your permanent residence is in Maine.
Also, track your days actually worked in MA, so you report the correct percentage (if you don't always split your time 2/3).
