SIPP lump sum reporting in SATR (not finding proper section)

Hello All, I took a single lump sum payment from my SIPP in 24/25 tax year. I got 20% withheld. The lump sum was my only income that year (I am retired) and it is under the taxable limit, so I am supposed to get all the withheld money back. I am trying to fill out my SATR for 24/25, but I am stuck: there is no "pension section" where I can report this income anywhere. In the "Tailor your return" section they talk about foreign pension income only, my SIPP is UK. Please help me find the section in SATR, where I can report the SIPP lump sum and the money withheld. I read the WIKI's could not find the answer. Thank You!
