I filed an amended tax return for 2020 in 2022. I will get more of a federal and state refund back now. Should I include this refund in 2021 taxes or 2022?

As I was filing my 2021 taxes (it is now March 2022). I realized a mistake in my 2020 taxes. I amended them and sent in a 1040x and state amendment. I will get an additional refund from both federal and state. Do I need to include this additional refund on my 2021 taxes or my 2022 taxes?
