Hello, @sterretjie143-gm. I'm here to help you connect your bank account to QuickBooks Online (QBO).
Before linking an account to online banking, you need to create the account and then connect your bank in QBO.
Here's how:
Click Banking.
On the Banking page, select Add Account.
Search for your financial institution and select it from the list.
Enter your User or Login ID and password for the financial institution's website and hit Continue.
Complete the security verification steps your financial institution requires and click Securely connect.
Tap the Account type dropdown menu to choose either a Bank or Credit Card account. If you haven't already created the account, you can select +Add new to create a new account.
