I received a P800 in summer 2022 prior to registering for self assessment. As a result, tax owed for 2021-22 was deducted from a refund I received for a previous tax year. Where do I enter this tax payment already made for 2021-22 on my 2021-22 self assessment?

Hello The final tax calculation of my self assessment done using HMRC recognised software indicates a small amount owing, but my 2021-22 P800 indicates I have already paid this exact amount as it was deducted from a repayment for tax overpaid in an earlier year. Was I supposed to enter this amount somewhere on the TR or SA110 form to bring my tax owing to zero? Thanks for your help
