1. You're going to file a part-year return instead of your regular Massachusetts return. When you entered the information into TurboTax at the start of the filing process hopefully you told the system that you had moved from Massachusetts to Texas. When you go to file your state return the system will enter that change in residency so that the Massachusetts return that is generated will be a part-year return.
2. When you enter the W2 into the system and scroll down to the bottom for "State Taxes" there is the option to 'Add another state'. Click that option. Then you will have two each of boxes 15, 16 and 17. Enter the information in the first set of boxes exactly as you have it on the W2 that you received. Then change the amount in box 16 to be the amount that you earned before the move. Now, in the second state box put Texas in box 15 and the amount of salary that was paid after the move in box 16. Leave box 17 blank.
