Bank linking

Hello there, Alexh0306.

You'll want to ensure to categorize your account transactions properly.

The possible reason why the credit card transaction shows in your bank account is that it was categorized in your bank account.

Please make sure to categorize your account transactions properly.

Here's how you can undo the transaction:

1. Go to Banking menu and select your credit card account.
2. Click the Categorized tab.
3. Locate the categorized transaction and click Undo under the ACTION column.

You may check out this article  about assessing your business finances: Categorize and match online bank transactions in QuickBooks Online.

I've added this article that you can use in the future: Change the bank account linked to your QuickBooks account

If you have any questions managing your QuickBooks account, I'm here to help you find an answer. Enjoy the rest of your day!

So we have unlinked and relinked trying different banks because 3 different ones show up. It still shows the credit card transactions that have no association with the bank account 

This is not the impression we want you to experience when using Online banking, Alexh0306.

I've checked here on our end and there's no reported case about this one. I appreciate you for performing some troubleshooting steps to get this sorted out. We can try creating a bank rule that helps us automatically categorize transactions for you. Here's how:

1. Go to the Banking menu
2. Select the Rules tab.
3. Tap New rule.
4. Enter a name in the Rule field.
5. From the For dropdown, click Money in or Money out.
6. From the In drop-down, choose the bank or credit card account.
7. Set the rule conditions. Decide the transaction must meet All or Any of the conditions. You can add up to 5 conditions.
8. In the Conditions fields, specify whether the rule applies to Bank text, Description, or Amount. Then select Contains, Doesn't contain, or Is exactly to decide when how QuickBooks applies the rules.
9. Select the settings for the rule. Hit the Transaction type, Payee, and the Category to apply.
10. Press Save.

See the Setup bank rules to categorize online banking transactions in QuickBooks Online for the steps and details. Then, try accessing the Banking page to check if the credit card transactions are no longer showing. We can also manually upload transactions into QuickBooks Online (QBO).

I'd like to know how you get on after trying the steps, as I want to ensure this is resolved for you. Just reply to this post and I'll get back to you. Have a great day ahead.
