Can I add another bank account to quick books from the same bank i already have an account with and how ?

Hello there, enquiries-holdth.

Yes, you can definitely add an account from the same financial institution you've connected before. All you need to do is add the register to your Chart of Accounts or connect it directly. Here's how to connect it in QuickBooks:

1. Go to the Banking menu.
2. Choose Connect account if this is your first time connecting, or Link account if you've already created one.
3. Search for your bank. 
4. Press Continue. Then sign into your bank by entering your banking username and password.
5. Follow the onscreen steps to connect. Your bank may require additional security checks. It may take a few minutes to connect.
