I don't want you to re-check the bank transactions since you've already reviewed them, PurpleJay.
It looks like you've manually refreshed the bank accounts in QuickBooks Online Self-employed (QBSE). If so, let me give an idea how this works.
Once you connect a bank account, the program automatically downloads the data. Manually refreshing it may cause duplicates. Possibly, this is the reason why more than 20 bank transactions are showing again in your online banking.
I'm here to help you fix this. You can exclude the duplicate transactions to remove them from the tax year calculations in the Home screen. Here's how:
- Go to Transactions on the left pane.
- Select the duplicate transactions.
- Click the Exclude button at the top.
Here's an article for the complete steps in excluding data: Exclude or delete transactions.
