According to my screen, you are using the Online version of TurboTax. Did you use the online version last year. Did you log in this year using the same exact credentials you used last year? Maybe you deleted your tax return from your online account last year?
In order to import data from your 2020 return into your 2021 tax return, you must log in using the same exact credentials you used last year. Additionally, last year's tax return must be in that account in order to import the data from it. If you deleted the 2020 tax return, then you have to re-enter everything from scratch again.
