I am completing my 2021/22 self-assessment. I started receiving a private pension in January 2022 and the P60 from the company shows that I have paid £160 tax for the period to April. However, I also received a lump-sum in January 2022 but this isn't shown on the P60. I believe that part of the lump-sum is tax free? Where on the tax return should I enter the lump-sum amount?
