I'm here to guide you on how to delete deposits in QuickBooks Online. 

Here's how:

1. Click on the Gear icon.
2. Select Chart of Accounts.
3. Choose Undeposited Funds and click View register.
4. Under the Ref No. and Type column, select the deposit.
5. Click Delete.

Once done, all the payments associated with the deposit will return to Undeposited Funds.
