How do I edit my unfiled 2019 1040 Form?

I printed my 2019 tax form, but discovered an error.  I can't find an option to make a change/edit on the form.  My only option is to amend the return, but nothing to amend because the original was never mailed/filed with the IRS.

 

Do I need to open a new Turbotax account and start over?

 

Thanks
