Deleting Lr photos in the cloud.

Hi.

Dummy here.

My Lr/Ps cloud is full, and it's difficult to do anything about it.

I don't even know where my photos are stored or I would try to delete all my cloud storage.

I can't see a Lr folder on my phone, and they're not stored on my PC.

I keep spending time on my phone and PC deleting photos, but when I return they're still there.

When I use my Creative Cloud app on my phone it only shows a few months of photos.

I think I might have managed to delete quite a few but I've still got the red cross symbol for exceeding my limit.

I'm surprised how clunky this system is from a premium software company.

Can anyone point me in the right direction?

Cheers.
