Why is a payment to my credit card posting twice to Quickbooks, once as a payment and once as a charge?

Hello there, @frontdeskAA.

Thank you for posting in the Community. Allow me to help share some insight about deleting the duplicate transactions added to the register.

You may have added transactions on the Banking page that already existed in QuickBooks that's why it's showing as a duplicate in the register. To fix this, you can Undo both the charge and payment in the Bank Register to remove them. 

After that, instead of adding the payment, you need to match it to the transaction that's already created in your account to avoid duplicate entry. Let me show you how: 

To start, let's undo the accepted transactions: 

1. On the left pane, select Banking.
2. Under Bank and Credit Cards, select your account.
3. From the Reviewed tab, locate the transactions.
4. Mark the checkboxes for the duplicate transactions.
5. Click the Undo button.
6. Click Continue to confirm.

Both transactions are moved from the Reviewed tab to the For Review tab where you can select the payment, and match it. 

Here's how:

1. On the Banking page, select the For Review tab.
2. Locate a transaction with one or more possible matches to review. The matching transaction appears in the CATEGORY OR MATCH column.
3. If the match is correct from the Action column, select Match, to accept.

Finally, you can follow the steps provided by my colleague, Rasa- LilaM to exclude the charge in the For Review tab and to remove it from your downloaded transactions. 

The following article contains more details about this process: Add and match downloaded banking transactions.

That should point you in the right direction. Please know that I'm just a post away if you have any other questions about deleting duplicate transactions in your QuickBooks. I'll be happy to help you further. Have a great day ahead.
