Hi there, @andrewtilling.
To isolate this issue, I suggest clicking the take action symbol. This way, we know what action is needed to solve this.
However, if you're unsure about the action that needs to be done, then I suggest contacting our support team. They have the right tools to check your account from a secure environment. This way, they can further investigate why you can't send your vat return. Let me guide you how to contact them.
In your QuickBooks Online (QBO) account:
- Go to the (?) Help icon.
- Click Contact us.
- Enter a brief discussion about your concern.
- Click Let's talk.
I've also added these helpful articles for additional reference:
If you have any other concerns or questions, don't hesitate to leave a comment below. I'll be around to help.
