How to Purchase

I am living in Germany and previously had purchased the Turbo Tax CD on Amazon and had it shipped to my home address. Since the program is no longer available on CD, I tried to purchase the download online. As part of the registration process to purchase, a home address is a mandatory field and it is only possible to enter an address in US or Canada.  Can the program be purchased in other countries, specifically Germany or do I need to find another solution.  I have used Turbo Tax since 2016 and would like continue if possible.
