If you do not wan to use TurboTax to prepare your tax return you can just abandon the account. No one else has access to it; nothing will happen with it. You can clear out any information you have entered:
If you have not registered, paid or e-filed you can clear and start over --- or just clear and do not start over.
CLEAR AND START OVER
