Thanks for getting out back to me, DGS1.
I appreciate you trying my recommendation for many times. However, since you're still experiencing the "Unable to add the item to list" message, I recommend calling our phone agents.
I'll add again their directory hotline for easier reference:
- Visit this link: https://help.quickbooks.intuit.com/en_US/contact.
- Select QuickBooks for Mac.
- Select your QuickBooks version.
- Select a topic.
- Click on the Get Phone Number button.
They can perform some steps with your company file if you permit the screen sharing tool. Through this, they can gather information about the error message and come up with the necessary fix.
Please keep me posted on how the call went. I'd like to make sure this is taken care of. I'm still here to help you more if you have other concerns.
