How to input payments for being a carer into the self assessment form

I am receiving money for acting as a carer for a disabled relative. How do I record this in my self assessment? I contacted the DWP who are the ones making the payment, but they weren't able to confirm the Employer name nor the PAYE reference that I should use.

Hi M G,
This should be declared under UK pensions, annuities and other  
state benefits received.
Thank you.
