Hi there, @prolandscapes.

I appreciate you for sharing the details of your concern. I'm here to help you with handling disputed payments in QuickBooks Online.

Yes, you will be notified via email about the chargeback notices or retrieval requests. The email gives you clear instructions for what to do or perform next. Usually, disputed payments/chargebacks can happen for a variety of reasons. They may be the result of a mistake, fraud, or an unhappy customer. 

To review the status of your payments, you can log in to your Merchant Service Account.

Here's how:

1. Sign in to the Merchant Service Center.
2. From the Activity & Reports menu, select Transactions. 
3. Choose the Show advanced options, which allows you to do a more specific search using information like transaction ID and expiration date of the card.
4. Select Search. The default Payment Type is Card. If you also have check processing on this merchant account, change the type to Check to view these transactions.
5. Tap the Transaction ID to display a detailed view of a transaction. You will also have an option to print the report or export the data as a .csv (comma-separated value) file.

For the reconciled payment, you can keep the record and ask the customer for another payment. Or, delete it and pay the invoice again. However, you have to redo your reconciliation to keep your records accurate.
