Is there still a "lookback" to 2019 (or 2020, or 2021) earned income to calculate our 2022 earned income credit?

No not for 2022.

 

 for the Earned Income Credit—-the rules are back to the “old” rules—

Those under 25 and over 65 without children are not eligible as they were uniquely in 2021.   And you cannot use your income from any earlier tax year to get the EIC for a 2022 return.  There is no “lookback” for 2022.  EIC for 2022 will be based on the income you earned by working in 2022.
