How do I update TurboTax CD/Download?
Although you can update over a wireless or dial-up connection, it's best to use a wired, high-speed connection to speed things up and minimize the possibility of data corruption.
Select Check for Updates from the Online menu in TurboTax (Windows) or quit and reopen the program (Mac). If new updates are available, you'll get a message to download them.
If you get disconnected while updating, try again and our update will pick up where it left off.
Windows users: Download a manual update if you're having trouble updating from the Online menu.
