Why is my COVID disaster distribution still being counted as income 4 years later? I paid the taxes on full balance with the last payment in 2022 tax year.

I took a disaster distribution from my 401(k) in 2020 due to COVID.  I paid taxes on it in the 3 tax years following - 2020, 2021, and 2022.  This year, 2023, it is still adding a third of the distribution amount as income even though the three years are done.  How do I correct this?
