Not sure how to answer question regarding Maryland withholding tax

Maryland requires income tax withholding for any compensation paid to individuals for personal services.

Turbo Tax Business product for MD State. It is asking whether we filed these returns but it is not clear which returns it is looking for and what is meant by 'personal services'.   Is this referring to the withholding for our W2 employees?  Or is it referring to individuals OTHER THAN our employees?  Please clarify so that I can answer the question correctly.
