I need to know the profit or loss for each product I sell. I entered the cost and the sales price for each product

Ask and you shall receive, @hanaya.

While there isn't a directly relevant version of the Profit and Loss report for individual Products and Services, you can compare a couple different statements to get the information you're seeking. See the steps below to get started:

The Profit - Sales by Product/Service Detail

1. From QuickBooks Online, navigate to the Reports tab.
2. Type Sales in the search bar and select Sales by Product/Service Detail from the pane below.
3. Set the Report period to the date range you need to know the profit for, and click Run report.

The Loss - Purchases by Product/Services Detail

1. From QuickBooks Online, navigate to the Reports tab.
2. Type Purchases in the search bar and select Purchases by Product/Services Detail from the pane below.
3. Set the Report period to the date range you need to know the loss for, and click Run report.

By comparing the information in these reports, you can get the profit and loss from each individual item you sell. I'm including a quick video example below in which I compare these numbers for last year:
