Hello Fishyfillet, Thank you for reaching out, we're sorry to hear that the chat was ended. There should be a warning before any chat is shut down and that is usually only down when the chat is resolved or inactive. Your chat record will be on your account and any chat agents can also look up your chat history so you should not have to start again from scratch. We can see they have noted the account as follows
Upon checking on the account, normally the other business income set up on your tax profile won't show up on the profit and loss but instead will show on your taxes. It will add up to your net profit so basically, your net profit is around 6000 pounds then if you will add your other business income it will exceed the personal allowance. In other words, the other income that you have declared is just for tracking purposes, to know your current tax rate.
Any questions we'd be happy to help further or we can ask the agent you dealt with to contact you via email if you prefer
