As long as you haven't paid or registered yet, you can use the Clear & Start Over account feature to remove your TurboTax data.

Here's how: 

1. Sign in to TurboTax Online (can't? Go here) 
2. Continue your/take me to my return.
3. Go to My Account (upper right) and select Clear & Start Over.
4. When asked 'are you sure you want to clear your return?' answer yes
