@ bellantoni   "How can I find my itemized Schedule C deductions in my Fed Tax return?"

Are you asking how to see the Schedule C Worksheet that has more details than the Schedule C itself?

Have you already efiled the return, and if so, has it been accepted?

Or is it still in preparation?

Using the Online version, you can look at the Form 1040 even prior to paying, by using these steps.  Click on Tools in the left menu column.  Then in the popup choose View Tax Summary.  In next popup, look for the tab "Preview Form 1040."  Scroll down until you find your Schedule C.
