How do I correct a transaction that is showing as an expense but should be income

Thank you for posting here on the Community page, wyeconsulting-gm. 

I'm here to help you correct the transaction in QuickBooks Online.

You can reclassify this transaction if it's still in the For Review tab. This way, your financial records are accurate in QBO. I'll guide you on how. 

1. Go to Banking from the left menu.
2. Select the For Review tab. 
3. Locate and open the transaction. 
4. Choose the appropriate income account from the Category drop-down. 
5. Click Add. 

If the transaction is already in the Reviewed tab, you'll have to undo it. The system will move it back to the For Review tab so you can categorize it to the correct income account. 

Once done, I recommend reconciling your account. It helps ensure your account in QBO matches your bank statement. Visit this page for more information: Reconcile An Account.
