I don't have a crazy tax situation, just some freelancing, so I usually used freefillableforms.com because I didn't want to pay for TurboTax. For some reason it errored out when submitting this year and would not let me re-submit it, so I had to use an alternative.

Ended up using FreeTaxUSA and was pleasantly surprised. Was way easier to enter all my info in than TurboTax, and pulled up the same refund amount. I don't see why I would want to use TurboTax when the free alternative is free and easier to use.
