Missing Federal Tax Computation Worksheet (Sorry, but accidentally put this under state tax filing originally so re-posting here)

I'm looking at the Qualified Dividends and Capital Gains Worksheet line 22 and trying to determine how that number was calculated. In my case since line 5 is more than $100,000 it says to use the Tax Computation Worksheet but I find no such thing. If I search forms, I find a form by that name for New York but not federal. Where is the federal version?
