I put all of my information in and was about to review, but then I noticed that there was a charge for this free filing service. So I checked back through to see if I checked a box that I shouldn't have, by starting over and making sure I clicked the free spot. But then my max federal amount dropped significantly! By like $400! Even though I entered the same numbers on my W-2, so what's the deal? I have been using Turbo tax for years,, but now I might as well try somewhere else.
