Hello @Ravina6
Are you looking for the section where you can put your company IBAN details or just where to enter your company name and details? Presumably you've clicked on "manage" since this opens up the section where you can add your company details?
Take a look at this Airbnb link that explains step by step how to enter company info and come back if this doesn't solve your problem!
