Hi Anna, thanks for getting back to me. Selecting Undo on a bank transaction in the Categorised bank tab will move it back to the For review bank tab (of your connected bank feed).
Transactions in the For review bank tab don't post in QuickBooks until they've been added or matched. From here, you can review the transaction, making sure the correct category is selected, before adding/matching.
If you undo and then re-add the same transactions (that were previously reconciled) you can then re-reconcile your account following the steps provided above and the difference will be zero.
If you need any further guidance, please do get back in touch below and we'll be happy to help further. Have a great day!
