If the booking comes up, click "Passenger and Documents" on the left, then select "E-Ticket and document numbers" that appears. Choose "Send e-ticket receipt", select/enter your email address.
In a few minutes you should receive an email, among the content of which is a full list of the Surcharge, Tax and Levy codes and the amount of each.
Thank you, this is super helpful. I've done so and the total taxes on that receipt is £651.99, o/w £268 is YQ/YR. Unfortunately it doesn't make up the full total though, but I'll do some more investigating, perhaps this only is the total for the AY codeshares.
