Exceeding Pension Annual Allowance and self assessment

I received a pension savings statement in Jul 2023. It advised me that I exceeded by annual allowance in 21/22. I am trying to add this information to my self assessment tax return. Should I add it to my current 22/23 assessment or should I modify my previously submitted tax return for 21/22? Many thanks in advance.

Hi alison c,
Please refer to:
HS345 Pension savings — tax charges 
If you exceeded your annual allowance figure in 2021-22 then your 2021-22 return should be amended to include the pension savings charge.
Thank you,
