Trouble filling RentGuard form - Self-employed and do own accounts

Hi! I am self-employed and do my own accounts so I am unable to complete the ‘accounts/employer’ page on RentGuard. I have no employer and can prove my income using my Paypal account. Any suggestions how I can complete that form? I’ve also contact RentGuard. I’d love to get this done asap!

The normal thing to supply would be your tax computation and tax year overview from your HMRC account.

Don’t know if that applies to rentguard though.
