There are a couple of reasons why transactions can show as duplicates in QuickBooks Online, Roadstarrepair.
First, let's check if a recurring transaction template is automatically adding the transactions to your bank register. Here's how:
- Go to the Gear icon and choose Recurring transactions.
- Review the list if there are templates that are causing the duplicates.
- If you found one, click the drop-down list beside Edit and choose Delete or Pause.

Here's an article about this process for more details: Duplicate transactions when using a recurring template.
Next, review the Audit log report. This records all account activity, including the name of the user who added the transaction. Here's how:
- Go back to the Gear icon and select Audit log.
- Choose a date in the Date change field, then select All transactions under Events.
- Look for the duplicate transaction, then click the View link under the History column.
