Again, the signed form is saved on your computer (typically as a PDF), uploaded to the program, and then attached and e-filed along with the rest of the return.
Frankly, I'm not sure where the confusion lies since the form cannot possible be signed within the program itself. Rather, it must be printed out, signed, and then scanned and saved to a folder on the user's computer. As a result, the user will always have access to the form unless the user deletes it.
