I am doing a 10 column worksheet and I have a credit $ amount in the Income Summary account in the Adjusted Trial Balance. Do I move that to the Income Statement or the Balance Sheet section of the worksheet?

Why do you have an Income Summary account at all on the Adjusted Trial Balance?

What have you put in this account?

I figured out that it goes to the Income Statement. The reason there is an income summary acct in the trial balance is because Ending Inventory (on the books) and Ending Inventory (via a hand count) is adjusted through the Inventory and Income Summary accts in this project. The adjusting entry ends up being the difference between the 2. Does that make sense to you? I am probably not describing it correctly... Thanks for all of your help.

What you are saying is that you are:
Dr. Income Summary
Cr. Inventory.

You should be Dr. COGS, but if the project tells you to debit Income Summary, then you are doing it correct.

And under that, Income Summary would go on the income statement to lower your net income by reducing your revenue amount to get a gross profit total.
