Step by step in applying and payment

I need guidance on online application and payment for endorsement.

I clicked on endorsement, it took me to home office Page to create account and make payments.

At home office page, I am only seeing already endorse category visa application and also asking to pay for health insurance first, What should I do from here?

You must have selected that you are applying for stage 1 and 2 at the same time. What link did you use?
