@JakailaLO, your answer is partially correct, but does not actually address the issue.
The article you linked is the standard procedure to print a preview copy from the CD version, and that procedure does print (which I was not having any difficulty finding), but the printed forms still did not have the Federal mail-in instructions summary page. The forms printed without that summary sheet.
Unfortunately, this does not solve the fundamental software defect of NOT printing the filing instructions and summary page for the Federal filing.
I believe this has to do with first selecting electronic filing and starting that process then reverting to mail-in. Which is what I did.
Fundamentally, there is a software defect which causes there to be no mail-in summary page printed after the e-file process user interaction has reached a certain point. After that, going back and re-selecting the print for mailing option does not clear the e-file flag and no Fed summary is generated.
Unfortunately, there is no way to submit a support ticket reporting this bug beyond posting on this social forum.
Can you submit a bug report for us to the TurboTax programming team to have this repaired? Clearly, I'm not the only one who found this bug.
