Hi talena@wintersda,
Welcome to Community! Although QuickBooks Online enables you to set up your sales tax agency and rates, there currently isn't a way to set up the MTD connection so you can submit your VAT returns electronically. If this is something you would like to see in future updates, please feel free to submit a suggestion to the Development Team.
If you have any other questions, please don't hesitate to reach back out. We would be happy to help!
