How can I go back and remove turbo tax self-employed and see what my taxes look like with turbo tax deluxe (what I used last year)?

The only way to remove the Self-Employed version is to downgrade. You can downgrade if you have not already paid or attempted to e-file/registered. Instructions are below. Please note that downgrading requires that you clear all information in your account and start over.
