Where to declare income on P2P type investments that are not true P2P

I have various P2P investments and also some on platforms that are not true P2P, but work very similarly. They do not fall into the HMRC definition of P2P and I cannot claim loss relief etc on them. Do I declare the income with the P2P in 'Additional Information' box 3, or as general interest with Banks and Building Societies. Or somewhere else?

Hi,
Yes declare with the P2P details.
Thank you.
