Each year, TurboTax offers a discount if you enter via Fidelity.com's Tax Center. I used TurboTax Deluxe which ended up costing just under $50 for filing federal and state forms.
This year was the first year I've used TurboTax on Linux. I was worried at first because when I first signed in, TurboTax displayed a page with the warning
Your operating system and/or Web browser do not meet the TurboTax Online system requirements.Intuit supports Firefox on Windows and Mac OS X, but not Firefox on Linux. I continued anyway despite their warning that I should have "upgraded" my operating system or browser:
If you continue without upgrading, we may not be able to assist you with any issues you might encounter.It turned out that I had absolutely NO problems using TurboTax online with Ubuntu Linux 6.10 and Firefox 2.0. They might as well just support it.
This year I am getting a federal refund, but I owe twice as much state tax. For some reason, not enough state tax is taken out of my paychecks. I still need to figure out why.
