@Gemma360 if you go to transactions you can download a CSV file (excel format) of revenues and fees for whatever period you require. I am surprised you have hit the VAT threshold and, if you have, why you are not charging VAT on your listing.
In future it is far easier to track all bookings, nights stayed and Airbnb fees through a manual spreadsheet. We also track all expenses so that the tax return at year end is a doddle.
