Hello, feelingsmitten.

Thanks for coming back to the Community. Also, I appreciated the effort of following the steps provided by my peer @Catherine_B.

You can pull up a Sales by Product/Service Detail report to show the SKU and Description. Just simply customize the report by adding SKU and Description on Rows/Column tab. 

Here's how:

1. Go to Reports from the left menu.
2. Click Sales by Product/Service Detail section.
3. Choose Customize at the upper right of your screen.
4. Under the Report period field, click the Custom field, then enter the date range.
5. From the Rows/Columns tab, put a checkmark of the SKU and Description tab.
6. Hit Run Report.
