Yes, you can do that.  But TTax makes it somewhat difficult to find.

On the screen where it asks if you want to e-file READ ALL information CAREFULLY, especially the smaller or faded print.

Also, look carefully at the selections, there should be a 'radio dial' type selection (a circle with a dot in the center).  The DEFAULT option is to e-file  --simply select/click on the 'other' radio dial option, to select print/mail.

NOTE:  There may be a second screen where you have to make the same selections to confirm your choice.
