Hello there, @jfogal.
Let me give you an overview of what is happening.
The Invoices in QuickBooks Self-Employed are for tracking purposes only. They don't affect your business and tax reports. Hence, you got zeros on your business income and owed taxes.
When you receive the invoice payments, make sure to do a deposit for it to show under the Transactions page.
You can use this link for more information: Manually add transactions in QuickBooks Self-Employed.
Though you can manually track sales tax in QBSE, they still won't appear on the reports.
The only way to reflect them on the reports is the Transactions page. You can use this link for reference: Manually track sales tax in QuickBooks Self-Employed.
Feel free to look into these resources for more details in handling your transactions:
Let me know if you need anything else. I'd be glad to help. Take care!
