Get your taxes done using TurboTax

I believe there is a glitch in the system. Why does TurboTax automatically use 2019 wages to calculate earned income credit instead of allowing the customer to use 2019 or 2020? For some reason being single, 2019 wages $62,891, 2020 wages $33,162, and 2021 wages $21,169, and I still do not qualify for the earned income credit. I do not understand. Please advise.
