I've just now changed a LOT of numbers in my 2017 return. The tax owed didn't change and I'm sure it should have. Is there a key combination or something that forces a recalculation, like alt-R ? Thanks.
There's no recalculate key combination. TurboTax recalculates automatically. You can always step through the interview again and check for errors, but it is possible that the items you changed did not affect you tax liability.
Amazing that I'm just seeing this in July, AND I have the same problem -- I exited and updated Turbo Tax and re-opened the form with new data that should have triggered new tax liability and still no change. What's wrong and how do I fix it?
