How to remove Cost of Sales (sub category) in COGS section of Profit Loss Statement. Its affecting the Profit/Loss at the end?

I'll share insight on your query about the Cost of Sales (COS) in the Profit and Loss report, @b653_2.

Since COS is a sub-account of COGS in your QuickBooks Online (QBO) company, then you can expect it to appear in the report. If you want to change the amount in COS to a different account, follow the steps below:

1. Go to the Reports tab, then search for Profit and Loss.
2. Click on the amount beside the COS account.
3. Tap the transaction you can see on the list to open it. 
4. Take note of the products and services in each transaction.

The next thing you need to do is open the Products and services page. It's where you can change the expense accounts for these products and services. Here's how:

1. Highlight the Sales tab, then select Products and services.
2. Look for those products and services in question. Click the Edit link beside them. 
3. Scroll down and locate the Expense account drop-down menu.
4. Change the expense account to what you want to use instead. 
5. Hit Save and close.
