Deducting payroll taxes vs withholding

[user17604831070]

I am a sole proprietor who has employees. Monthly I pay federal income tax withholding and SSI (for 941), Medicare. I also pay state Withholding, SDI, and Unemployment insurance quarterly. Do I deduct employee’s payroll federal withholding I paid monthly by adding it as part of wages? If not, where? 
Also, I see from other answers we deduce our half of Medicare and SSI from Schedule C “Taxes and licenses”. This doesn’t budge deductions much and I wonder if I understood correctly. 

Thank you!
