Duplicate bank connection

Welcome to the Community space, @Sianwestmancoat. I know the duplicate transactions have become challenging on your end especially when you click the bank connection an error prompt shows. Allow me to guide you on what we can do to fix this.

If you don't want to see transactions from a bank account anymore, you can hide them. This stops QuickBooks from downloading new transactions, and you keep all the existing data:

1. Open QuickBooks Self-Employed in a web browser.
2. Select the Profile ⚙ icon and then Connect bank.
3. Find the account you want to hide.
4. Under the Show Account section, switch it OFF.

For additional info, check out this article: Delete bank and transaction data in QuickBooks Self-Employed.

The articles below will also help you transfer between accounts, add older and exclude transactions in QBSE:

• Transfers between accounts in QuickBooks Self-Employed.
• Add older transactions to QuickBooks Self-Employed.
• Exclude or delete transactions in QuickBooks Self-Employed.
