Hi there, SimonP2.

We can go to the Prepare VAT return page to view the exceptions made from the edited transaction. Here's how:

1. Go to Taxes and select VAT.
2. Find the return you want to submit.
3. Select Prepare return under Action.
4. On the Prepare VAT return page, check Exceptions between Amount and Total amount.
5. Click the amount to view the transaction.
6. Then, you'll be routed to the VAT Exception report.
7. After that, click the amount again to check if they had VAT calculated.

If you need to adjust the amount, I recommend speaking to your accountant or an accounting professional before making any changes to ensure that your reports are correct after the adjustment.

Once ready, follow the steps below to make one:

1. Go to Taxes and select VAT.
2. Find the return you need to change and choose Adjust to increase or decrease the amount as necessary.

For more details about VAT exceptions, please see this article: VAT exceptions and reports in QuickBooks Online.

Once ready, you can submit a VAT return to HMRC using MTD in QuickBooks Online.

Feel free to ask if you have more questions about VAT. We're here to help and will gladly assist whenever you need it.
