Thanks, Maya D.
I couldn't find it until TurboTax pulled a new set of updates and restarted, and then it appeared as "Qual Div/Cap Gn".
There's still no quick link on the 1040/1040SR Worksheet "Smart Tax Worksheet" line H, but it's fairly obvious from the check boxes above that it's from the "Qualified Dividends and Capital Gain Tax Worksheet", and most folks will connect that to the abbreviated name above.
