TurboTax may or may not do Form 8615 correctly. When Turbotax can't do 8615 correctly, they have no explanation. After six calls, they told me to just file the incorrect return, which would have underpaid my taxes. When I told Turbotax that I wasn't comfortable knowingly filing an incorrect return (underpayment), they told me their guarantee would take care of it. (Does anyone believe that? Turbotax never gets back to you on anything). I believe Turbotax is simply hoping the IRS doesn't catch the error their software causes. This way, (1) Turbotax doesn't have to fix its problem (2) the IRS likely gets cheated, or must do extra work to avoid being cheated, and (3) if the IRS does catch the error, the taxpayer may get tagged as a cheat and get a $ penalty, as well. Plus, remember that 8615 is on your child's return - how would you like your child to have "underpaid taxes and was penalized" in all the databases of the world?
