When using TurboTax Software any prior year software by TurboTax needs to be removed from the computer or it can cause issues when installing, running, or working within the new software. I am including an FAQ on how to uninstall the old version of TurboTax software for Windows. If you are using a Macbook or any Apple computer to uninstall the software you would just locate the old software in your Applications folder and drag it to your Trash can. I would also empty the trash can if using an Apple computer. And also restart your computer after the old software is removed.
