Welcome to the Community, @Sunneva. To make sure we're giving you the best advice, could you tell us a bit more about what you're looking to set up? Are you asking about specific QuickBooks URLs, or is it something else?
Just a heads-up: as long as your QuickBooks account is UK-based, you're all set to ensure your taxes are filed correctly. If you're specifically looking to get VAT up and running, this guide is a great place to start: Set up and use VAT in QuickBooks.
Feel free to leave a comment below if you have any other questions.
