Since you may need to install other software in the future, you could purchase an external CD/DVD-ROM device, if you wish, which costs maybe $20-25, or you can contact TurboTax Support to request a download.
TurboTax Support is closed until Wed., December 27 due to Christmas holidays.

How do I contact TurboTax?
Use the form at the link below to schedule a callback. However, you won't be able to proceed until they are open, so there's no need to try until Dec. 27. This time of year they are open 5AM-5PM Pacific (8AM-8PM Eastern) Mon-Fri.
