To manually reverse your General Journal entry from the previous month
Use this procedure only if your transactions are changeable. See What are changeable and unchangeable transactions? for more information.
(As an alternative, you can mark the “Transactions CAN’T be Changed; They Must be Reversed” option in the Preferences window to make your transactions unchangeable, then complete the procedure To automatically reverse your General Journal entry from the previous month. If you do this, be sure to unmark the “Transactions CAN’T be Changed” option again once you’re done making your reversing entry.)
The General Journal Entry window should be displayed.
