Hi there, @2014.
Thanks for posting here in the Community. I'm here to help share some details about pulling up information under the Saved Filing section for your forms.
The saved filings in QuickBooks Desktop is dependent on the location of where the company file is stored. Since you've upgraded from QuickBooks 2016 to 2019, it's possible that you've changed your company file location. To access your saved forms, you may manually pull them up if you still remember where the file is located.
To learn more about saving forms in QuickBooks Desktop, please refer to this article: Process, print, and save QuickBooks Desktop Payroll tax forms. Also, you may read through this article about moving files in QuickBooks desktop for your future reference: Move QuickBooks Desktop.
This should it!
You've got me here if you need more help with pulling up information on your saved filing in QuixkBooks Desktop. I'd be happy to help. Have a good one!
