Thank you for participating in the discussion, Mark. I can provide information to access the original data or backup copies of your QuickBooks Desktop files. This way, you can revisit and thoroughly review your transaction records.

You can download the free trial version of the 2021 program, which lets you explore some of your past data. However, know that this trial is only available for 30 days, and after the allotted time frame, you will no longer have access to the company file. During this time, it's crucial to ensure the backup file is up to date to keep compatibility with newer versions of the Desktop application.

I highly recommend checking the View and download your QuickBooks Desktop data section in this article for instructions on how to download the free version of QBDT and Restore your file.

Another option to have 24/7 access to your records is to move from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO). By doing so, all your files are stored in cloud storage, allowing you to review or modify them anytime and anywhere. For more information or assistance, please see this page: QuickBooks Desktop discontinuation support.

In addition, here's an article to gain insights on QBO's workflow and how you can optimize your business processes: Get started with QuickBooks Online.

I'm always ready to help you again if you have other questions about QuickBooks. I also encourage you to communicate with me in the comment section so I can jump back in and lend a hand in addressing your inquiries. Stay safe, and have a nice day.
