Salary goes on a W-2, not a 1099-MISC.

There should not be a Schedule C.

Any expenses should have been (1) paid they corporation (so the deduction would be on corporate return) or (2) paid by the shareholder then reimbursed under an Accountable Plan (so the deduction would be on the corporate return).  Other possibilities is that shareholder paid the expense and it is treated as a capital contribution or loan.
