You can still install TurboTax if you don't have a built-in or external CD drive. Start by setting up your TurboTax account if you don't already have one with us. Then, contact us and a Support Representative will push a download into your TurboTax account. Once that's been done, simply sign in to My Downloads to download your TurboTax software.
