It doesn't matter what you call the category.  You need to assign your category to a tax line item number.

To check the tax line assignment open the Category list by either clicking on the Category Icon or go to Tools-Category List or Ctrl+Shift+C. Then select the category and right click on it to Edit it. Click on the Tax Reporting Tab and check the box for Tax related and pick a Schedule C: tax line item.

Here is a screen shot of mine.  As you can see I named my schedule C categories with the schedule C line number.  You can use any name you want.  Then you assign each category to the tax line.
