Hi @jubella,
Let me help you out with your question.
I assume you're already aware of an ongoing investigation with the connection between QuickBooks Online (QBO) and MTD accounts.
With regards to your second concern, what the previous support representative told you is correct. At this time, QBO doesn't support the option to submit an annual VAT return. The workaround has been provided by the phone support representative as well, and that's to divide your VAT returns into quarters.
Please leave a comment below if you have any other questions.
