Your personal itemized deductions on a Schedule A and Standard Deduction have no bearing whatsoever on reporting your self-employment income and expenses on a Schedule C.
To enter self-employment income and expenses using the TurboTax online editions you must use the Self-Employed edition. The Self-Employed edition also supports entering rental income and expenses on Schedule E. The Self-Employed edition also supports entry of pension/retirement income reported on a Form 1099-R.
