how do I undo ALL bank reconciliations

Hi there, Stacey. Undoing all reconciled bank accounts at once is only available for QuickBooks Online (QBO) Accountant.

Otherwise, if you have the other regular QBO Account, you'll need to manually undo-reconcile the transactions one by one from the registers.

To manually reconcile it, go to your Chart of Accounts and locate the reconciled account. Select View register, then look for the column that has a check mark on it. Then, click the R until it makes it blank to make it un-reconciled.
