Why arent federal taxes beingtaken out oy my paycheck?

Do they take out any deductions?  Like for Social Security and Medicare?  They might be paying you as an independent contractor on a 1099NEC and not aW2 employee.  Or each check is to small to take any withholding out.  Ask them again.  Ask someone else in payroll.

if you're being treated as an employee it is mandatory for the company to take medicare and social security taxes out of every paycheck even small ones. if these are not being taken out then they are treating you as an independent contractor. you'll file a schedule C and owe self-employment taxes and possibly income taxes when you file your 2022 return.  It's bs that the payroll department can't answer your question.  did you turn in a w-4 when you began working? yes, you should be treated as an employee. no, they're treating you as an independent contractor
