I am currently having this exact problem. All interest and dividend income save MA bank interest, is being allocated to MA, despite being a part year resident. Turbo Tax automatically allocated wages and earned income from my W-2, but there is no way to do this manually for the non MA portion of interest and dividend income. This, despite purchasing the plan that allows a CPA to review my return with me. He cannot figure any other option but the aforementioned work around.
The work around is a poor option as it requires a paper return rather than being able to e-file. Part of the reason I pay for Turbo Tax in the first place is not to encounter these issues.
