You must enter some basic personal information in the Personal Info section of the program. Click Upgrade, located near the top of your screen. In the pop-up window, scroll down to the bottom, select TurboTax Plus, and click the Upgrade Now button. If you want to include a state program with your order click on State Taxes and complete some of the state section.

To pay the TurboTax online account fees by credit card, without completing the 2016 return at this time, click on My Account at the top of the online program screen. Then click on Print Center.

On the next screen it will ask if you want Audit Defense, if you do not want this option just click on the Continue button. The next screen will ask for all your credit card information so you can pay for the account.
