You have three basic options.
1. Return the CD to the store, and buy turbotax as a downloadable installer from a retailer such as Staples or Amazon.
2. Contact customer support, and ask them to put a download in your account after they verify you bought the CD by mistake.
3. Find or borrow another Mac with a CD drive, and copy the Turbotax installer to a USB flash drive, then use the flash drive to load the software to your own Mac.
