I qualify for the earned income tax credit. I usually get it but this year I did not. only change this year was I filed my 1098T but this shouldn’t matter. Why is this?

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.
