@Linda1274,
Sorry, it is just called "reservations", it is an item from the horizontal menu at the top, showing your upcoming or finished reservations (there is a tab above the reservations list to choose this)
The direct link is probably (i guess, because i am on the Dutch Airbnb website): https://www.airbnb.co.uk/hosting/reservations/
And the three "dots" are at end of each line, as stated before, giving access to the pulldown menu, where the VAT invoice is located.
Best regards,
Emiel
