Let me share a few information on how Online Banking works, travishulmeconst.
When you connect your bank to QuickBooks for the first time, the Banking page only downloads up to 90-days worth of bank transactions.
The system updates the bank transaction list automatically. Though, you can also do a manual update if you don't receive any updates.
- In the Banking page, click the Update button.
- Enter your Multi-Factor Authentication (MFA) credentials.
- Click Continue update.
If you need more than 90-days worth of bank transactions, you can ask a valid WebConnect file from your bank. Then, import the file to QuickBooks Online. Feel free to browse these articles on how to import the file:
I'd be glad to offer some help if you need more assistance with this. Have a great day!
