Welcome to the Community, @NikiFMT.

QuickBooks Online (QBO) has recently made some changes to the location of the invoice status history. Let me guide you through the process of checking the status of an invoice. 

Here's how to see it:

1. Go to Sales, then select Invoices.
2. Click on any invoice you want to view the status.
3. A pop-up window will appear. Under Invoice Activity, you'll find the status.

Moreover, after receiving the payment of the invoice, you can now record it to QBO.

Please let me know if you have any further questions regarding the invoice status you sent to your customer. I'm here to assist you anytime.
