How to file electronically and submit a signed form 8283 and inventory on paper?

When I file I must submit an appraisal with form 8283, and that form must be signed by me, the receiving institution, and the appraiser. If I file electronically, TurboTax will automatically submit the form, but without the necessary signatures and inventory. How do I submit the signed form and inventory if I want to file electronically, and how do I make sure that they are associated with the proper electronic filing? Or am I barred form filing electronically because of this one form?
