I have similar issue. Started in MD, moved to TX. I set the residency in MD to be Part Year and put in the dates -- they are there each time. I even have the W2 Line 16 set to MD with the State Wages amount.
The MD tax due is way off. When I look at the output (PDF) and can see Form 502 has none of the part-year residency info I entered, and line 12 has no value, so TurboTax is having me pay tax in MD the entire year.
