Self Employment details

Hello, many apologies if this is the wrong avenue for this question. I'm currently filling out my self assessment form, and wanted to double check some of my self-employment details, However I'm having a hard time finding where that information is stored on my account, is there an easy way for me to access this information? Many thanks!
