I deleted an already reconciled line item from a few months ago. How do I go back to that month to reconcile it?

I'm here to help re-enter the deleted line item to the reconciled account, PatCarol.

Before we start, any changes to the reconciled account, like deleting a transaction, can affect the balance. To fix it, you need to enter the line item you've deleted so the balance is accurate.

You can start by retrieving the deleted entry using the Audit log feature in QuickBooks Online. It will help you get the original transaction's date, amount, and other details. Take note of the information since you're going to enter again the transaction.

After that, you can pull up past reconciliations and review them so you know if balances are correct. Here's how to view a reconciliation report:

1. Go to Reports.
2. Type Reconciliation Report in the Find report by name search bar.
3. Select Reconciliation Reports.
4. Select the Account for the reconciliation report you want to view.
5. From the Report period drop-down arrow, choose the reconcile period.
6. Select View Report.

Then, you need to create the transaction and post it to the correct bank account. Once done, go to the register and manually reconcile the entry.

Let me guide you through the steps:

1. Go to the Accounting menu.
2. Select Chart of Accounts.
3. Find the account holding the transaction, then click View register from the Actions column.
4. At the very top of the list, select the Add journal entry, Add deposit or Add check ▼ drop-down.
   
   
5. Select the transaction you want to add.  
6. Fill out the fields to complete the transaction.
7. Under the checkmark column, keep clicking the field until you see an “R.” 
   
   
8. Click Save.
