Can't reconcile bank account after migrating account from Desktop to Online

I appreciate you for sharing a screenshot,  jellis11. It's my priority to ensure you can reconcile your account.

There are several reasons why you encountered an error message when reconciling, and I've listed them below:

• An incorrect opening balance was entered.
• Transactions were added which are older than the account's opening balance, and its original opening balance entry was never edited to reflect the change.
• A user manually reconciled a transaction, causing it to not show up on your next reconciliation.
• Someone edited, deleted, moved, or unreconciled an already reconciled transaction. It changes your ending balance for the last reconciliation, which impacts your beginning balance the next time you reconcile.

You'll want to start by reviewing the opening balance and confirming it's correct. Afterwards, you can check your bank statement.

Here's how:

1. In QuickBooks, go to Accounting, then Reconcile.
2. Review the account. 
3. Confirm you're reconciling the correct month(s).

Next, if your account is connected to online banking, confirm all downloaded transactions have been matched and categorized before you begin reconciling. Doing so ensures you have the final correct beginning balance. Also, click the We can help you fix it option to open a discrepancy report.

Review it and use its details to decide if and how to make necessary changes. Intuit recommends talking with whoever made the changes before editing them since they may've been made intentionally.

Once you know you need to make corrections, review each transaction on your report one at a time:

1. Click a transaction's View option to see the history of changes to it.
2. Review your Change Type column. It will inform you what type of change was made.
3. Perform your edits based on the message displayed in their Change Type column. If necessary, refer to Intuit's list of change types to identify what each one means and what you'll need to do.
   

After reviewing everything on your discrepancy report, the Total Discrepancy Difference should be $0.00. Be sure to check your account's beginning balance again in QuickBooks. It should match the beginning balance shown on your bank statement. When you're ready to proceed with reconciling, click Resume reconciling.
