What is a manual update?
If you can't update your TurboTax for Windows software using the normal update method, you can download and install an executable manual update file.
You can even download the manual update onto a thumb drive so you can transfer the update to the computer TurboTax is installed on.
Manual updates are available for TurboTax for Windows federal programs (Basic through Business). They're not available for the Mac or TurboTax State programs, nor can they be used to convert an older version of TurboTax to a newer one.
