Normally, when a state requires an attached form (in this case, the federal return also requires it), an electronic copy is included in the XML file that it e-filed to the state.
XML is a tagged data format, and not like the PDF that you read.
I am not positive that with all these last second tax changes that this is happening for Maryland, but normally, if you needed to attach a paper copy of a form to your return, TurboTax would tell you so.
