How do I delete and start over in the CD version of Turbotax 2018?

I am not using the on-line version.

You don't necessarily do so from that exact file.

What you do is go up to the upper-left corner of the screen  (Windows..not sure where it is on a MAC) and click on

<File

<<New Tax Return

...and that starts a new one all over again....after you get started with it, you can either overwrite the old file, or give it a new name and leave the old one intact for reference purposes.
