Thanks for the note, @Carl. This may help with other problems, but I don't believe it will resolve the underlying issue here because I do not have multiple state tax returns. The underlying issue seems to be that nonresidents that sold Maryland property are getting erroneous TurboTax calculations on Maryland nonresident income tax returns. Specifically, severely overstated subtractions from income listed as "BB Net subtraction modification to Maryland taxable income when claiming the federal depreciation allowances from which the State of Maryland has decoupled" are originating on Maryland forms 500DM/505SU (decoupling modification/nonresident subtractions from income) and then showing up on Maryland form 505 (non resident income tax return). This is leading to all of, instead of most applicably a partial amount, of Maryland's taxes withheld at sale showing up as a refund. This discrepancy needs to be resolved. I will take @Critter-3's recommendation and seek live professional assistance.
