We are aware that the Registration for TurboTax is not working. Our team is working on a solution as we speak.
Since registering your copy of TurboTax isn't mandatory to complete your taxes, you'll still be able to use TurboTax to prepare your return and will be able to register later once the issue is resolved.
When you first open up your CD/Download version of TurboTax, simply select "Register Later" and you can continue with completing your taxes. We apologize for the inconvenience.
Take care & stay safe ~ Kim
