Thanks for getting back to us with additional details, SDM2.

For now, we're unable to add the Undeposited Funds account in the Bank Accounts section of your Dashboard. This is because this account is not a real bank, and only serves as a holding account for undeposited payments. 

In the meantime, you can continue the usual steps that you've been doing to see the balance. Here's an article that talks about this account for more details: What’s the Undeposited Funds account?.

You'll also want to inactive the accounts that you no longer wants to see in the Chart of Accounts. Follow these steps on how to remove them: Delete an account on your chart of accounts in QuickBooks Online.

I'll be around if you have other questions.
