It could be the transactions were entered twice or downloaded twice, @accounting452.

To verify this, let’s check your Audit log and see who made those changes. Let me show you how:

1. Sign in to your QuickBooks Online (QBO) account.
2. Navigate to the Gear icon.
3. Select Audit log.
4. Click the Filter drop-down menu.
5. Personalize it to All users, select Show all events, or thick the Transactions box.
6. Then click Apply. 
7. Select the duplicate transactions and delete them.

Additionally, if the transactions were downloaded from your bank account, we can exclude the duplicate ones. Here’s how:

1. Go to the Banking or Transactions menu.
2. Click the Banking tab.
3. Select your preferred bank account and go to the For review tab.
4. Find the duplicate transactions and Exclude them.

You can also read through this link for more details: Exclude a bank transaction you downloaded into QuickBooks Online.

If the transactions were already added to your chart of accounts, let’s go open your account and delete it from there:

1. Go to the Accounting menu.
2. Select Chart of Accounts.
3. Locate your preferred account and the View register link under the Action column.
4. Click on the duplicate transactions and select Delete. 

I’d also recommend getting in touch with your accountant for additional guidance in deleting those transactions. This way, we can ensure your book is well accounted for after making these changes.
