Hello @george36,

The error message you received is related to the integrated connection with HMRC in QuickBooks. Let's consider refreshing it so you can prepare and submit your return with no issues. Let me show you how.

1. Go to the Gear icon.
2. Under YOUR COMPANY, select Accounts and Settings.
3. Select Advanced.
4. On the Making Tax Digital section, select Learn how to connect.

In addition, here's an article you can read to learn more about how you can connect with HMRC: Authorise QuickBooks to interact with HMRC - MTD for small businesses.

Lastly, I've also included this helpful article for the steps that'll help prepare your return: Submit a VAT return to HMRC - MTD for small businesses.

If you have any other questions, please let me know in the comments. Stay safe!
