Next year, if your only MD income is wages and no MD taxes were withheld (that's what MW507 does for you as DoninGA mentions), in Personal Info tell TT that you didn't make money in any other state (since MD can't tax your wages as a VA resident). In fact, don't mention MD to TT at all. Selecting *Yes* to "making money in any other state" tells TT that you need to file a nonresident return for that state.
