Was there any kind of link within your confirmation email to access your download?
One other way you "may" find the download is to go straight to the homepage of TurboTax.com. The first topic on the header bar says, "Products and Pricing". Hover over that topic, and you'll see one option to "Access My Downloads". You may try that option.
If you still have no luck, please contact TurboTax Customer Support during business hours for assistance. A Support agent will be happy to assist you. Use the info I'm linking below to contact Support.
