I own an S corp. I didn't setup payroll. So I won't be receiving a w-2. I made withdrawals and have paid esrumtaed tax payments. How do I report this on my 1120s?

I own an S Corp and have taken salary. I never setup payroll be a use I was told that all I had to pay was self employment tax by making estimated tax payments quarterly. Now I found out I had to setup payroll  for wages. My question is how do I report the wages and estimated tax payments made on my 1120s return for next year. Is it too late to setup payroll now and pay payroll tax ?
