QB desktop cost of goods is wrong after update

Hey there, @EL34. Glad to have you here.

To resolve this issue, you'll need to rebuild your file. No worries, it takes less than 15 minutes and can be completed in just a couple clicks. To do this:

1. Go to the File menu. Then hover over Utilities and select Rebuild Data.
2. On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
3. Let the tool repair your file. It may take some time. QuickBooks may seem stuck, but as long as you can move your mouse, the tool is working.
4. When the tool finishes, select OK.
5. Open QuickBooks and your company file. Everything should be fixed.

If the issue persists, continue following the steps outlined in Resolve data damage with your QuickBooks Desktop company file.

That's it! Please touch base with us here if there's anything else you need, I'm determined to ensure your success. Thank you for bringing us your questions.

Ok, thanks
I'll do that after I close tonight and let it run
I'll report back

Ok, Rebuilding the data did not work
It found one issue and fixed it, but the P&L is still wrong
All the cost are incorrect

This is the one issue it found

I also did both of the steps on this page
Still no good

Thanks but the people from QB on the phone were useless
They want me to buy QB2020
They had no idea why the cost of items were wrong.
Total waste of my time and about an hour on the phone

Since then I have figured out where these exaggerated items cost are coming from
The average cost is way off for the item below that I am using in a test sales receipt
I created a sales receipt and sold one item and the cost is .20 each
I ran a report that shows income and cogs for that one sales receipt
The cost shows as -29.29 for that .20 item
I looked at the item and the cost is correct at .20
But the average cost is showing as 29.28667Round that up and you get 29.29
The average cost is where the issue is
Note that the on hand is -339

Screen shots below show this 

I found this post here that seems to be the same as my issue with average cost
