I would like to delete this account. I have another account with turbo tax and accidently made a new one today

Hi,

There is no option to delete your account. Once you've paid or registered, we're required to store copies of your return. Just use the original account and let the other one go dormant. You can also clear the information from your unused account using the "Clear and Start over" feature. 

For further information you can refer to the following link:
