You misunderstood me. There is a big difference between using TurboTax online version and a download or CD version. In the online version you are working "in the cloud", on their server, and subject to wifi and network glitches, etc. Your computer is just acting as a connection, but neither the program nor the data is stored there.
The download or CD version is the same program, but the whole thing is on your computer: program + data, and you are working independently of the internet until you e-file. And you can access the program, print out forms, etc. even if you are off line.
