Can't see where to change my income

HurlyBurly

I receive UC LCWRA and also a private dependent's pention, I've been told to adjust it manually (usually automatic) but I can't see where on the website to input the info.

Under "Report a change in circumstances" there is:

Work and earnings, Health, Living with a Partner, Caring for Someone, Bank account, Children and other people who live with you, Contact details, Personal Details, Where you live and what it costs, Money savings and investments, Request to close your claim.

I tried going through "Work and earnings" but there's nothing in there about other income.
