I'm sorry, but I have never seen that happen.
I can only speak for the Windows version, but in TurboTax for Windows, even in a brand new return the Filing instructions form is there, but is blank for a lot of information. I just tested it. Right after opening a new return and before making any entries, if I go to Forms Mode, then "Filing Instructions" is already listed as a form in the list. It is a default form that is always present at any stage of preparation. However, it originally says "File by Mail" as a default until one actually goes to the FILE section and chooses efiling. At that point the title changes to Electronic Filing Instructions. But the form itself should always be there in the list.
I'll see if SuperUser
@macuser_22 has any comment on what you are experiencing in the Mac program in case there is a different way it is handled there.
Does your desktop software show that your efiled return has been accepted? You can also use this tool to check:
