Get your taxes done using TurboTax

I just spent 6.5 hours on the phone with TurboTax after I was unable to get a 2nd download for TurboTax Deluxe.  The upshot was that the first person who utilizes the software must download must enter whether it will be for Mac of PC.  Then ALL REMAINING DOWNLOADS MUST ALSO BE USED FOR THE SAME machine type!  My son downloaded for his MAC, then I wasn't able to download for my PC.  This is a BIG change that no one appears to know about.  I was advised I could purchase another TurboTax product or purchase another computer.  From 5 users to 3, then not able to use on multiple machines?  I haven't found this addressed online.  Would LOVE your input!
