I appreciate you for providing complete information and a screenshot above, ddiguru1. This leads me to the right details about the issue.
Right now, we have an ongoing investigation about the scripting error when sending email in QuickBooks Mac 2020. Rest assured that our product engineers are actively working to get this issue fixed.
Let me lay out the reason of this matter first before we proceed. This usually occurs if the permission is not granted to QuickBooks when its opened for the first time after installation.
To resolve the issue, you'll have to check your System Preferences. If you're able to view QuickBooks, then you can grant it access to mail. If you're unable to see QuickBooks on the list, I'd recommend consulting your IT guy or a Mac professional. They can help you with your privacy settings to include QB on the list.
Moreover, you can also use the Custom email preference. This will let you tell QuickBooks who your email provider is, and allow it to email directly without the use of the Mail app.
In addition, I want to ensure you're in the loop about the investigation's status and its fix. I'd suggest contacting our QuickBooks Desktop Support team so you'll receive updates via email.
Thank you for your patience regarding this matter. Please let me know if you have other concerns. I'm just around to help.
