I couldn't get prior years' tax history into my 2020 Tax History Report either. I didn't cut and paste, as another person mentioned above, but I did something similar. I clicked on the Forms icon in the top left corner of the downloaded TurboTax version and clicked on the Tax History Report in the list of forms. Then I dug out my printed copy of 2019's Tax History Report for all of the prior years' history. Then I tabbed my way through the 2020 Tax History report that's in the downloaded version and typed in all of the appropriate numbers by referring to 2019's Tax History Report (2020's numbers were already filled in, of course, from using the program). Manually entering the numbers wasn't as time-consuming as it may sound, and everything I entered saved to the Form as I worked. Then I went back to Easy Step (in the top left corner of the downloaded version) and when I went to Print and Save my 2020 return, my Tax History Report was properly filled out for every year. Hopefully, it will all transfer next year to 2021's Tax History Report. It's odd that so many of us ended up without any Tax History.
