I also signed up for Windows 10 extended support.
I tried using TurboTax online a couple of years ago but found it unusable. Navigation was so poor that I couldn't go back and fix an incorrect entry. I also didn't like that it appeared to be saving all of my data in the cloud instead of to a local ".tax" file.
At this point, if I need to use online tax software I might as well start from scratch and research all options.
