Deductions & credits

"However, you do have the option of printing the statement, signing, and scanning to a PDF that can be attached to your e-filed return."

 

Can you elaborate exactly how to do that?  e.g. How do you attach a PDF to the return that can be efiled?    I am not exactly sure that is what you meant.  I would like to sign the statement, scan it and then attach it to the return that I can efile. I dont see a place in turbotax that asks for a pdf that I can place prior to efiling, 

 

Thank you
