It looks like my earlier post was deleted so I'm reposting. Here is the answer to the question that I have been asking but has not been answered by anyone on this TurboTax thread.
"
The Massachusetts Department of Revenue informs us that this W-2 is compiled in error, and the correct course of action is to request a corrected W-2 showing only the amounts in Box 16 attributable to the state in which they are earned, not each state for which the wages are taxable.
If the employer will not issue a corrected Form W-2, there are a couple options available to complete your tax return reporting the correct amount of wages that are taxable to Massachusetts. "
