Thanks so much for the fast reply! It turns out I had done those steps exactly. Unfortunately the the PDF download for 2021 does not contain the same Tax Summary or Two Year Comparison pages as are containes in my 2020 filing PDF. I use Turbotax online only, no desktop software, and each year I elect the same tax prep service level. Maybe thes summary "features" were discontinued or somehow I did not elect to have them included (no memory of that). No worries, I will extrapolate my 2021 data and make my own chart(s).
