Upgrading is a one-way street. Once you've upgraded, you can't downgrade back to your original version.
- With your return open in TurboTax, select Upgrade TurboTax at the very bottom of your screen, towards the right.
- In the new window, select the version you'd like to upgrade to and select Upgrade Now.
- Follow the onscreen instructions to purchase the upgrade.
- When finished, continue working on your return. You don't have to go back to the beginning.
