I'm here to help share some information about the default Undeposited Funds account in QuickBooks Online. The Undeposited Funds account is an Other Current Asset account that’s automatically created by QuickBooks to record funds received by a company that is not immediately deposited in a bank account.
If you're using the 3-rd party, you may want to check with them for the settings.
There is no real setting option to remove the Undeposited Funds in the QBO. If you're manually recording customer payment, you will select the "Deposit to" field to your bank account. It will stick until you change it.
From the Banking For Review tab, you can also select "Find Match" for the Undeposited Funds payment/deposit and match it.
