Hello, @Susan607. 

Thanks for reaching back out and giving some additional details. 

Since none of the troubleshooting steps are working and the check box isn't allowing you to put a check in it, I recommend contacting our Customer Support Team for further assistance. 

1. Go to the Help menu. 
2. Press the QuickBooks Desktop help/Contact us. 
3. Enter your question. 
4. Tap Get a callback. 

Please keep us updated on how the call goes. I'll be waiting for your response!
