Good day @Juan C Lozano,
Allow me to join in the discussion and share what I know about these numbers.
The PTIN is for paid preparers. A paid preparer is the one who prepares federal forms (941, 944, and 940), like an accountant. If you don't have a paid preparer, don't worry about this info.
The FEIN is a number assigned by the federal government to an employer to track payroll tax liabilities and payments. Please note that this is not the same as your Social Security Number.
The easiest way for you to get a FEIN is to apply online at the IRS website.
You can view this article when you start to create your payroll. It provides the steps on how to run a scheduled payroll, override taxes or deductions, and print pay checks.
In case you have any more questions, let me know by leaving a comment below. We're always here to lend a hand.
