Thank you very much rjs. You are correct - I am looking at the Form 8615 Schedule D Tax Worksheet in TurboTax. And thank you for the explanation that TurboTax always uses the Schedule D Tax Worksheet. I cannot find that sentence you quoted in the Form 8615 help but that clears that part up as to the why. And yes, line 11 of Form 8615 is zero.
I found my error, thanks to you. I entered an incorrect value on one of the lines on the Qualified Dividends and Capital Gains Tax Worksheet, and that threw the remaining calculations off. After correcting, I do indeed get the same result per your statement, in comparing TurboTax's Schedule D Tax Worksheet resulting tax and the Qualified Dividends and Cap Gains Tax Worksheet resulting tax. Thank you!
