The fact that you're a part-year UT resident doesn't matter.
From the Utah Code:
"If you are a Utah resident or part-year resident with income that is taxed by Utah and another state(s), the District of Columbia, or a possession of the United States, you may be entitled to a credit for income tax paid to the other state(s)."

Did you claim credit on your part-year resident UT return only for the portion of MD taxes you paid while you were a UT resident?
