How can i add a second checking account to my quickbooks?

Good day, laurenllc2019.

You can follow these steps on how you can add the second account:

1. Go to Accounting > Chart of Accounts.
2. Click the New button.
3. In the Account window, select Bank from the Account Type and choose Checking from the Detail Type.
4. Enter the Name, Description, and Balance.
5. Hit the Save and Close button.

For reference, here's an article: Add an account to your chart of accounts in QuickBooks Online.

If you want to connect this account for online banking, then you can open this article for the instructions: Connect bank and credit card accounts to QuickBooks Online.

I'm also adding these articles if you are adding the account as sub-account:

• Create subaccounts in your chart of accounts in QuickBooks Online
• About bank or credit card subaccount setup

I'm just a post away if you need anything else. Take care!
