Welcome to the Community, @radomira. Let me share some ideas with you regarding duplicate transactions in QuickBooks Online (QBO).
If you connect your online banking to QBO, transactions will be automatically downloaded to your account.
One possible reason why you have duplicate amounts is when your online bank downloaded the transaction and categorized it as a deposit. Then, you also manually recorded a payment for the same invoice.
Here’s what we are going to do. We will exclude the duplicate transaction that you manually recorded. To do so, kindly perform the steps below:
1. Go to the Accounting menu and select the Chart of accounts tab.
2. Find the account that has the reconciled transaction. Then select View register.
3. Find the transaction. If the transaction is reconciled, you’ll see an “R” in the checkmark column.
4. Select the transaction to expand the view.
5. In the checkmark column, select the box with the “R” until the box is “C”. This removes the transaction from the reconciliation.
6. Select Save.
7. Close the account register.
Then, go to the Banking menu and select Categorized tab. From there, you’ll see the two duplicate transactions. On your manually recorded payment, we have to clear that payment to enable us to match the deposit from your bank to the invoice.
Once done, let’s go to the For review tab again and look for the deposit, then hit Match. We can then reconcile the transaction back to its register.
Furthermore, I added this following article for your reference when reconciling your account in QuickBooks Online.

Thanks for dropping by the Community, @radomira. Let me further assist you in sorting out this issue about your transaction in QuickBooks Online.
If you have duplicate transactions in the Banking page, you can delete them. Ensure they're actual duplicates before you proceed, so there aren't any discrepancies. In this case, you can consult your accountant for further guidance on this matter.
First, undo the transaction if it’s reconciled.
From there, you can now delete the transaction.
