I have an opening balance discrepancy because I deleted a reconciled transaction. How can I fix this?

I've got the steps to help you correct your deleted transactions, gene. 

In QuickBooks Online (QBO), when we make changes to our reconciled accounts, we can correct this by recreating the deleted transaction and reviewing the audit log to use as a reference. 

Here's how: 

1. Go to Settings, and select Audit log. 
2. Look for the deleted transaction. 
3. Hit View. 

Then, the information will display on your screen, we can use that to re-create the transaction. 

After recreating the deleted data, we changed its status back to reconciled to keep our books organized. 

Perform the following: 

1. Go to the account register and find the transaction you recreated. 
2. Click on the blank field to mark it as reconciled - R. 
3. Click Save and yet to Yes to confirm.
