If you have an Advantage subscription where you received the TurboTax software each tax year in November of the year, you will also have a download in your account if your normal order is a CD.
Go to this TurboTax website to sign onto your Advantage account - https://accounts-tax.intuit.com/turbotaxadvantage
If you do not have an Advantage subscription and you order the CD from TurboTax, to get a download you will need to contact TurboTax support so they can push a installation file to your download account.
