To correct the submitted VAT return, you need to contact our Live Support team for assistance with unfiling and updating your records, @batthtransport.
Please know that these changes will show in your VAT Exceptions report. Check this article for reference: Create and manage VAT exceptions in QuickBooks.
After correcting the necessary information, you can manually mark the document as filed. Please note that QuickBooks is for recording purposes, and the actual money movement must be refunded to HMRC.
On the other hand, you can make VAT adjustments to correct errors on past returns.
Please let us know if you need further assistance.
