Thanks for following this thread, @Michelle170. As an additional insight, you'll need to restore your data on the same version and edition as the original file so it will show.

For instance, QuickBooks Pro 2015 backup needs to be restored to the same edition and year. You also want to upgrade the backup to the current QuickBooks version by jumping 3 versions. For example, you can restore a 2015 backup to a 2018 version.
