Completing online tax return for both employed and self-employed

fuzexi

Hi, 
I'm trying to complete an online tax return, and I am employed but also am earning a little "side hustle" which I need to declare, since it's over £1000.
I have registerd as self-employed and am now filling in the online form.
It's asking me for how much I earned from self-employment, so I have entered it. 
It then asks me for "any other business income", and I have put my income from employment in this box. Is this correct? Have I done it right?
At first I left it blank but then I got an error. 
I can't see anywhere else where it asks me how much I earned "from employment", is this because HMRC already know the answer to that?
I've attached a screenshot for clarity.

It is not correct. Go back to tailor your return and select the ‘Do you have any employment section? Complete this new section and include both your income and tax paid when asked.

Answer the following questions by putting ‘X’ in the ‘Yes’ or ‘No’ box.

 1 Employment 

 Were you an employee, director, office holder or agency worker in the year to 5 April 2021? Please read the

notes before answering. Fill in a separate ‘Employment’ page for each employment, directorship and so on. On each ‘Employment’ page you complete, enter any other payments, expenses or benefits related to that employment.
