Where should we enter the stimulus payments of $2,800 on the 2021 tax return?

We have received letter 6475 from the IRS. I entered the information that we received those stimulus payments of $2,800 in the Federal Review section. I do believe that they are not taxable. Where should I report those stimulus payments, under Wages and Income or Other Tax Situations, or where? I can't find any section to record it.
