We deleted a deposit that was inadvertently entered twice prior to our fiscal year end (6/30/19).  We didn't notice this error until August, after we had already filed our tax return 990.  When we re-ran the Balance Sheet this year (Aug 2020)  for the same period (7/1/2018 to 6/30/2019), the amount is off from what we reported last year by the exact amount of that deleted deposit ($220) and the amount is actually $220 greater than prior to deleting the transaction.  How can we rectify this problem so our accounting is correct?
