OK - this site is messing with the link in the earlier answer, so here is how I found it.
1. Go to the Intuit Turbotax page: turbotax.intuit.com
2. In the header of that page, select the "File your taxes" option which will open a list of choices.
3. From the list of choices, select "File your taxes for a prior year."
That should open the page letting you find earlier versions of the software.
