Yes, you can redo the previous reconciliations. @caleb_hanson.

Once you have your bank statements, compare the list of transactions with what you recorded into QuickBooks. If everything matches, you know your accounts are balanced and accurate. 

Here's how:

1. Go to the Gear ⚙ icon and select Reconcile.
2. From the Account drop-down menu, select the account you want to reconcile. Make sure it's the same one on your statement.
3. Check the Last statement ending date link. Ensure your bank statement starts the day after your last reconciliation.
4. Review the beginning balance. See to it that the beginning balance in QuickBooks matches the one on your bank statement. Here’s what to do if they don't match.
5. Enter the ending balance and ending date as they're written on your bank statement.
6. When you're ready to start, select Start reconciling.
