If you elected MTM, you have to file a paper return, with all your transactions detailed as an attachment to Form 4797, and no Schedule D.
TurboTax won't support a PDF attachment to Form 4797 during e-File.
You might get away with sending the details on paper copy to the IRS office in Austin, TX which is the place to mail transaction detail after you e-File.
Either way, you are mailing in the transaction details on paper.
