Hi there, scottchs.

Welcome back to QuickBooks Community. I appreciate you for providing detailed information on what you've done to accomplished what you need. I'll share steps to ensure that you're able to run the Statement of Cash Flows report with accurate details.

To ensure that rental payments are included in the report, you'll have to make sure that the summary report basis is assigned to Cash. This way, only the invoices that are paid will show because the entries are associated with payments based on the date of the amounts. Then, filter the report to Transaction Type and choose invoice and payment.

Here's how:

1. Click the Reports menu at the top. Then, choose Company & Financial and select Statement of Cash Flows.
2. Click the Customize Report. 
3. Go to the Filters tab.
4. Choose Transaction Type in the Search Filters field.
5. Choose Multiple Transaction types in the drop-down list and select Invoice and Payment.
6. Hit OK.
7. Click the Classify Cash button located in the upper right corner.
8. Choose the Company Preferences tab. Then, choose the Cash radio button on the Summary Report basis.
9. Click OK.

For additional information on how you can personalize the font and style of the report to show the date that you want to view, you can click this article: Customize reports in QuickBooks Desktop.
