Updated my credit card and it wiped pout my history.

Let me help you get it back, @mull1.

You'll have to reconnect your credit card again to get back the transactions. Also, when an account is disconnected from QuickBooks, all the unreviewed transactions will be deleted as well.

Reconnecting the credit card is the same process as how you first connected it. Let me show you how.

1. Go to the Banking tab and select Connect account.
2. Search for your bank using the bank name or URL.
3. Select Continue and enter your online banking login credentials.
4. Choose the account and the account type you'd like to connect
5. Click Connect.

 For more details, you can refer to this article: Connect bank and credit card accounts through Banking.

I've included this resource in case you're unable to see the latest transactions or encounter a bank error in the future: What to do if you see a bank error or your transactions won't download. 

Also, you might want to check out these articles to learn more about downloaded banking transactions and reconciling:

• Reconcile an Account in QuickBooks Online.

Update me anytime if you have any questions. I'll be right here if you need any help with the tasks in QBO. Have a lovely day!
