google analytics – Filter E-Commerce transactions by event

I have an event that fires whenever a user picks a specific payment method. It has an event category of ‘Payment Methods’ and a Label of ‘Finance’.

I am trying to exclude any of these transactions from my E-commerce report, ie. anyone who triggered this specific finance event.

I can’t see where to filter this in Analytics, or even how to create a custom report to achieve this.

Has anyone done anything similar? Thanks.
