Thanks! I looked at all the QB online help, including the reconciliation workflows, none of those address this issue.

I also unreconciled all 73 transactions individually, however that didn't do anything because the actual balance in the reconciliation needs to change.  Unreconciling the individual transactions in June doesn't allow me to start the June reconciliation over again.

The ending balance for June in QBO needs to increase by $100. The account is reconciled through December of that same year.   When I go to reconcile, it gives me the starting balance as the ending balance of my last reconciliation (December). So basically I'm just reconciling & unreconciling transactions without going anywhere.

How do I adjust the amount in the Petty Cash account and Run a NEW Reconciliation Report for June (etc...) with a different ending balance?
