Ok, so as long as you have not filed your return, the return can be cleared out. If you have not submitted or registered your return you can delete it using the following steps.
1. Sign into your account and select your current return
2. Select TaxTools on the bottom left and then clear and start over
This will clear out all of the information that you have entered.
