How to connect with a 2nd checking account with the same bank? I tried, but the response was already connected to that bank, choose a different bank

Let me share some information about connecting your bank accounts for Bank Feeds, cakefetish.

You’ll encounter an error message that the account is already connected if you're trying to connect both parents and their subaccounts in QuickBooks Online (QBO). In this case, we need to choose on what account you'll need to connect for your Online banking. If the transactions are downloaded to one account, just connect only the parent account. For transactions that are downloaded to the individual accounts, we can connect the subaccounts. 

Once you have decided, follow the steps below in adding or connecting your bank account:

1. Go to the Banking menu.
2. Tick Connect Account, or select Add account or Link account if you've already created an account.
3. Search for your bank. Then, select Continue and enter the username and password you use for your bank's website in the pop-up window.
4. Choose the accounts you want to connect (savings, checking, or credit card) to QuickBooks. 
5. For each account, select the account type from the dropdown. These are accounts currently on your chart of accounts.
6. Select the date range for the download. Some banks download the last 90 days of transactions, others go back as far as 24 months.
7. Press Connect.

When reconciling your accounts, we only need to reconcile the parent account since all transactions in the subaccounts roll up into it. See About bank or credit card subaccount setup article for more details about this one. Feel free to visit our Banking page for more insights about managing your bank feeds and reconciling accounts.
