Thanks for following up on this thread and trying the suggestions, victoriah1956.

Since none of the troubleshooting methods mentioned above did the trick I recommend reaching out to a member of the QuickBooks Desktop Support Team. Agents have specialized tools, like the ability to share your screen, to take a closer look to determine what's causing the PDF issues. They'll even be able to get the problem escalated further if need be. Here's how to get in touch with the team:

1. Go to Help, then select QuickBooks Desktop Help/Contact Us.
2. Select Contact Us.
3. Give a brief description of your issue, then select Continue.
4. Sign in to your Intuit account and select Continue and then Continue with my account.
5. We'll email you a single use code. Enter your code and select Continue. (If you have more than one account, select the account you want to use and then Continue.)
6. Select to chat with us or have us call you.

Please feel free to reach back out if you have any other questions. I'll be here to help in any way that I can.
