Can someone explain to me why quickbooks online only uploaded part of my bank statement? and is there a way to reupload a statement ?

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.

1. In the Banking page, click the Update button.
2. Enter your Multi-Factor Authentication (MFA) credentials.
3. 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!
