Licence code associated with another account

[JummyX]

I have always shared a licence code with my dad, we do not live in the same house and we always use way fewer than the 8 returns that come with the standard version.  This year, for the first time, when I went to active my TurboTax with the license code I am getting error message 608 "This license code is already linked to another account". 

I thought you could use one licence code on multiple computers.  Do I have to log in with my dad's account?  Will that affect me when I go to submit my return to the CRA if I am logged in with his account?

Thanks.

TurboTax Desktop for TY24 will have 1 account per license code. As of this tax season, you need to log into your TurboTax account or create one in order to use your software. This will help our customers, as it now saves your license code to your TurboTax account. Yes, you can download it on 3 computers using your TurboTax account associated with your license code. It makes the process much easier, as when you are logged into your account when downloading on a new computer, the license code will already be there for you to click on. 

You can still complete 8 returns as previously and NetFile them once NetFile is opened. Nothing has changed concerning NetFile. 

Thank you for choosing TurboTax.
