Scheduling delivery reports and saving them on your desktop or shared network is unavailable since it can only be possible if you send them through your email. Thus, you can either send your reports through email or manually download them if someone sends you a file.
If you're interested in how to set scheduled reports, you can utilize this material since it has accurate and detailed steps that can help you further: Set up and modify Scheduled Reports.
You can also browse and learn more about reports or other concerns that describe your situation: Self-help Material in QuickBooks.
Feel free to leave a comment if you have further questions about reporting or anything related to QuickBooks Desktop.
