Where can I find the detail of how Turbo Tax is computing my total income tax withheld?

The underpayment penalty screen (in other tax issues or other sections) gives me my total income tax withheld that is being reported on my W2.  This amount does not match what was withheld on my W2s.  I'd like to see the detail of how TurboTax is computing the total income tax withheld.

You wouldn't be able to see that in one place. Your tax withheld would be reported on your W-2 and 1099 forms typically. You would have to look at each form entry and add up the reported tax withheld to see what the total is.
