Hello there. @snrproductions.
I see how important to bring all your bank transactions to QuickBooks. Also, I appreciate you for performing the Update button.
Is this your first time to connect your credit card account to QuickBooks? If so, QuickBooks Online automatically downloads the last 90 days of transactions. Since you need more than 90 days of transactions, you can export additional historical transactions from the bank and upload them into your QuickBooks company.
First, download transactions from your bank by logging in to your bank's website. Then, follow the given instructions on how to download transactions and save the file on your desktop or anywhere you can easily find it.
Once done, upload them to your book by following these steps:
- Sign to your QBO account and select Transactions on the left panel.
- Click the Link account drop-down arrow.
- Select Upload from file. Then, click the file you've saved on your computer.

You can use these articles as additional reference in fixing bank upload errors, categorizing transactions after imported them, and the reconciliation workflow in QBO:
Let me know if you have other questions. I'm right here to assist you anytime. Stay safe and have a good one, snrproductions.
