Thanks for taking the time to reach out to the QuickBooks Community for support, @jeffrey10013. I'm here to help you get a copy of your check transactions with the descriptions.
When you export reports or lists from QuickBooks Desktop to Excel, the data will be exported exactly as it's stored in QuickBooks. You'll want to review and ensure you've mapped them correctly.
The data displayed in your description section on the file or bank feed transactions comes from the financial institution your account is with. With this, you'll want to contact your bank and request the full details.
Furthermore, I would like to know how you downloaded the statement into the program. Did you import the Excel file? Have you edited it on your end? Any additional information can help us narrow down this issue.
Helping you is my top priority. I'll be on the lookout for your response. I'm always available for you. Stay safe.
