Unfortunately, once the activation code is used in an account, it is not transferrable. To delete your second account, please follow this link: Contact Us. When asked if you wish to receive an email say NO then say "speak to a representative" then hold the line.

​​​​​​​Thank you for choosing TurboTax.

I believe we should provide an option there.  Because the code activated we still haven't filed TAX and just want delete the account and use the activation with another account. 

Or if you deactivate this license code and provide another license code that also would be good.  Please check if any possibility is there. 

Thanks,

When you contact the telephone support team they will be able to help you with your account and unfortunately the activation code cannot be used on another account.
