Hi there, tammy-dalton.
As mentioned by my colleague above, once you activate the VAT in QuickBooks Online, the system automatically creates the common codes. And, this includes the 20% ECS code. That being said, there's no need to create a new one.
All transactions that came from QBDT may still use the old VAT rate. However, you can also change the vat codes in the transaction using the default ones created by QBO.
Since the system won’t let you change the vat code that was imported from QuickBooks Desktop, I suggest contacting our QuickBooks Support Team. They can pull your account and may look to refresh the VAT codes to resolve this issue:
1. Open your QuickBooks Account.
2. At the top right, click the Help icon.
3. Click Contact Us.
4. Under What can we help you with?, enter your concern about the vat codes.
5. Click Let's Talk.
6. You'll be routed into the Choose a way to connect with us page.
- Start a chat with a support expert.
- Get a callback from the next available expert.
7. Select how you want to contact them and fill in the information.
