"...I got the same result as the LLC "

Then you've entered something incorrectly.  There should be NO S/E tax showing on your "test" return. DID you factor in the deduction of payroll tax expenses at the Corp level?

Don't forget to factor in the legal costs of incorporating, the cost of doing the Corp return, the cost of payroll processing, INCLUDING determining what the reasonable compensation amount should be, and the taxes due at the Corp level to the State (if applicable - CA has an $ 800 minimum).
