How do I get the TTX program to print an amendment and not print a total of 395 pages? This doesn't make any sense. Please help.

The "Print and Mail" page says "Select Print Returns and choose 'All official forms required for filing' to print out your amended returns and filing instructions."  When I do this I don't get any choice--I just get a dialog box saying TTX is getting ready to have my printer print out 395 pages.  See attached.  This does not make any sense.
