I think most people buy TT for their needs thru entire filing season which TT does very well, rather than for year-end estimation, it's well known to have a lot of updates thru January. I don't disagree with earlier comment about lack of disclaimer for those expecting fully working s/w at this point. Personally I've never bought it til January, and the prior year s/w was usually good enough with some allowance for the changes to deductions and tax rates, though the extent of the big bill changes makes all this more difficult this year.
Anyway if this enough for you to look elsewhere and other tools meet your needs anyway then have at it, you can request a refund from Intuit up to 60 days from purchase.
But if you really just need a tax calculator to do some year-end planning estimates there are simpler tools to do this, and come back to Turbo next year once we are in filing season and they are ready; try -
