Thanks for joining in on this thread, iambethlea.

I'll share some steps to help you update the credit card transactions.

Every night, QuickBooks automatically downloads the latest transactions from your bank. When an update seems to get stuck, an issue from the bank's end might be causing this, or you may need to complete some security requirements.

You'll want to follow the steps shared by my colleague Jovychris_A on this thread on how to manually update your bank in the Banking page. This helps update all of your connected bank and credit card accounts, and add your new transactions. 

I've got this sample screenshot for a visual guide:

After the update, try to review your transactions. If your bank is still not loading the new data, then I recommend signing in to your bank's website then check for any maintenance or security updates. In case you encounter any bank errors, you can check the solutions under Step 4 in this article: What to do if you get a bank error or can't download transactions in QuickBooks Online - Variant.

Moreover, you have the option to manually import your bank transactions using a CSV file. The instructions on how to do so is laid out in this guide: Manually upload transactions into QuickBooks Online. Then, start categorizing and matching the data.

In cases that your bank updated the new transactions and you get some duplicates, I've got this link with steps on how you can exclude them: Exclude a bank transaction you downloaded into QuickBooks Online. When you're ready to reconcile the bank account, feel free to watch the video tutorial here.

Please keep us posted on how things go after doing the update. We want to make sure you have the new data updated. Take care!
