Can anyone help me work out where on my delcaration des revenus to delcare from interest on UK bank accounts?

I’m feeling lost…

I’ve earned (paltry, double-figure only) interest on an ISA account and a savings account in the UK this year.

Where am I supposed to declare this on my delcaration des revenus? I can’t work out which box it’s supposed to go in.

Any help gratefully appreciated.
