Where did the TT brief yearly comparison cover sheet showing income, deductions, tax due, and effective tax rate go? How do I get to that?

The Tax Summary Worksheet will be included in the PDF download when you select to include all worksheets.

Click on Tax Tools on the left side of the online program screen.  Then click on Print Center.  Then click on Print, save or preview this year's return.  Choose the option Include government and TurboTax worksheets

This worked but it took a while to find the Print Center because you have to be in your return, hit Review, then find Tax Tools on left navigation, then click just the right place to open that drop-down to see Print Center option while getting hit with a couple promo ads wanting you to upgrade. All good but more painful than it should be.
