Is your Turbo Tax a version for Windows? if so it might run under the Wine
Windows Emulator, or Crossover Linux, but there is no guarantee. Wine is in
the Ubuntu repository, but Crossover must be purchased from
http://www.codeweavers.com/products/cxlinux/. It's $39.95 for the standard
edition and $69.95 for the pro edition. There is also a free 30 day trial
edition available there. If it works on your Windows software it should be
enough to get your taxes done anyway!
