Same issue here. I just purchased and downloaded TurboTax Premier 2021 (from Amazon), installed and updated the program, and transferred last year's return (*.tax2020 file), and yet no data transfers to the new return. On a Mac running OS 11.6.1 (Big Sur). I've been using TT for the last eight years and this is the first time I've encountered this (seemingly basic) issue. My only thought is with the typically frequent updates to TT that occur early in the tax year this will be fixed, but honestly, this should never have been released with this bug.
