Migrated from desktop to online version. When I reconcile last January, there is a $750 discrepancy. Can't access old account so no idea what it's from or how to fix?

Which QB Desktop year version did you use?

Hello, bufrecs. Thank you for reaching out to the QuickBooks Live Community. It appears you're dealing with the same discrepancy above. Managing your business finances is vital, especially during such transitions. Let's work together to identify the issue and ensure your financial records reflect accurately, giving you the clarity and confidence you need.

To begin, let's review your opening balance and transactions to check if some changes or amounts didn't add up upon migrating from your QuickBooks Desktop to your QuickBooks Online. Ensure all of it are correct. Once confirmed, you can use your bank statement as a reference to verify you're reconciling the exact account for the correct month.

Here's how you do it:

1. Go to Transactions, then select Reconcile.
2. Select the account that you want to reconcile from the Account ▼ dropdown.
