Get your taxes done using TurboTax

So I bought the downloadable version for an offline PC (for security) because it is literally advertised as not needing and internet connection.  " You'll be able work on your taxes, even if you're not connected to the Internet."

So if I understand correctly, to be able to use this product securely, without an internet connection, I have connect to the internet with said "Offline Only" computer??? The entire reason I bought this version was to specifically NOT connect to the internet.
