Thank you for posting your problem and solution. I too was receiving the same error message. As a consultant who never has inventory, I couldn't figure out what was causing the error...until I read your post. I searched for and found a very small negative expense (-$3). I don't know how it got there when it was imported from QuickBooks, I am now at the 25 minute mark from submitting the return, after receiving past rejections within 5 minutes. So, I am hopeful following your information solved the problem. Thanks again for your post.
