Getting started

@PaulAON As per the TurboTax Desktop Software End User Licence Agreement:

You may: (i) install and use the Software on up to three (3) computers; (ii) make one backup copy of the Software solely for archival or replacement purposes, which copy shall also be subject to this Licence Agreement; and (iii) print and/or netfile up to the number of returns included with the Software. Your valid licence code is required for all of the above. You understand and agree that any re-installations of the Software on the same computer (for example in the case of a hard-drive crash or replacement of your computer) will count as installations for the purposes of the three-computer limit above.

So if two people in your family can't share a computer with each other, then yes, someone will need to get their own copy of TurboTax Desktop.
