Not sure what to put for trading name

Hi, I'm just filling in my form to register for self-assessment for 2024/25 but just got confused by the trading name part. I started to teach Zumba classes in January 2024 but I also run a book blog which I have had for a few years even though it has only just started earning a small amount of advertising revenue but with the exercise classes I go over the £1,000 limit. My blog is completely unrelated to my exercise classes so for trading name should I list both my blog name and my trading name for my exercise classes?

Hi Michael,
Yes you will need to show both.
Thank you.
