Create a bank account in QBO called Cash Box. Then, make a transfer (New > Transfer) from Undeposited Funds (UF) to Cash Box for the amount of your opening balance equity (OBE) that you are leaving in the Cash Box. You should now have the 20 contributions and the amount of OBE that you're depositing sitting in UF. Go to New > Bank deposit and select the 20 contributions plus the Transfer and you should be all set.
