Hello @Merris-And-Bob0
Method 1 - To activate Professional tools, go onto your host landing page where you see Today, Listing etc. Top right hand corner you see your profile picture. Click on it and you should see Account and an option to activate Pro Tools.
Method 2 - on the Airbnb link page re Pro tools below, click on Account settings and that should redirect you to where you can activate the tools.

And we enter our local taxes such as tourist tax under Regulations but we are not in the same county so always a bit delicate to be 100% certain our interface is the same but a good place to start!
