Thanks @Mike9241 .
Your answer makes sense, it matches what TurboTax puts into the prior year column.
So qualified dividends are essentially included in two separate fields!
Once under "Qualified dividends", and once under "Total of your other taxable income and losses" (as it's labeled in the worksheet) / "Other Income and Losses" (as it's labeled in the Estimated Taxes EasyStep Workflow).
