Hi there, @buchanan.

I want to make sure your issue with 1099 gets resolved.

Your company file may be damaged that's why it doesn't let you change anything when printing or filling 1099 forms. Let's run the Rebuild and Verify Utility tool to fix data damage on your company file. Here's how:

1. Open your company file again.
2. Go to the File menu, then select Utilities and choose Rebuild Data.
3. Click OK in the QuickBooks Information window.
4. Wait until the repair is done. Then, click OK.
5. Then, go back to the File menu and select Utilities, then choose Verify Data.
6. Click OK if QuickBooks doesn't find any problems. Or Rebuild Now if it finds issues with your company file. 

If you get the same result, you can check out this article for more troubleshooting steps: Fix data damage on your QuickBooks Desktop company file.

If the issue persists after performing all the troubleshooting steps, I recommend reaching out to our QuickBooks Support Team. This way, they can further check on this matter and help you print/file your 1099 forms.
