Hi there, joneill1186.

Thanks for posting in the Community. I'm here with some insight to provide on how to get this straightened out right away.

Just a heads up, QuickBooks uses Weighted Average Cost to determine the amount debited to COGS when you sold your items. You can check out this article for more information about this: Understand Inventory Assets and COGS tracking

If you need to adjust the debited amount, then you could make a General Journal Entry affecting the Inventory Asset account and COGS. However, please be sure to reach out to an accounting consultant to ensure this is the best suit for your business. With Intuit's Find-A-ProAdvisor site, you can search for certified professionals in proximity to your ZIP code that can discuss options more personal to your business's needs.

That should get you going in the right direction. Let me know if there's anything else I can help you with. Thanks again for reaching out, wishing you and your business all the best!
