One connected bank account that is split into two in QB - how do I fix this?

I’ll help you with combining the two bank accounts in QuickBooks Online (QBO), @MHines2022.

In QuickBooks, if you have multiple cards associated with your account, we can set up the other account as a sub-account. We have the option to create a parent account and the others underneath it as sub-accounts. On the other hand, before connecting it to online banking, you’ll need to know how your bank sends the transactions you've downloaded.

Connect only the parent account if the transactions are downloaded to one account. Connect the subaccounts rather than the parent account if the transactions are downloaded to separate accounts. You’re unable to connect both accounts, otherwise you’ll get a message that the account is already connected.

Here’s how you can set-up an existing account in chart of accounts:

1. Go to the Settings and select Chart of accounts.
2. Look for the account you want to edit. Then, in the Action column, select Edit.
3. The next steps depends on your account set-up. If the Account window appears, proceed to step 4. Otherwise, if you see the Edit category window, you’ll need to switch to accountant view to change the account to sub-account.
4. Select the Is sub-account in the Action window. Then, select the Enter the parent account and choose the parent account you want to move the account under.
5. Select Save and close.
