According to the Comptroller of Maryland's website :
If a pass-through entity has a nonresident member and any nonresident taxable income, then the pass-through entity is subject to the Maryland income tax. The pass-through entity is taxed on the nonresident taxable income, which is the sum of the nonresident members' distributive or pro-rata shares of the pass-through entity's income allocable to Maryland.
A "nonresident member" includes a nonresident individual member (defined as a person or fiduciary) and a nonresident entity member. A nonresident entity member is a corporation or pass-through entity that is not qualified or registered with the Maryland Department of Assessments and Taxation to do business in Maryland or not formed under Maryland law.

The quote from the website above says that I have to pay MD income tax - that quote from the website does not anywhere say that I have to file that tax on the 510 (business return). As long as I pay it on the individual return, it should be fine? In any case, it is a pass through entity, and such entities aren't suppose to pay any tax on their business returns - always only on the individual return - it is so for the 1120S and the Colorado 106 (which is where I reside). TurboTax is telling me that I have to pay this on the 510D, and has prepared a voucher for me and everything. Please confirm that if I am paying this 5.75% MD state tax plus the non-resident 1.75% MD tax on my personal MD return on everything including the business side income, then I am good to not pay it on the 510 for MD.
