I have no knowledge of labor law, but I speak English and I'm a New York resident. It sure sounds to me like, in your case, your job site is your home address. It is the physical location where you do your job.
Additional attempted clarification from Colors-newyork.com:
What was your job location or job site unemployment?
Answer Expert Verified During a job interview you may be asked what
your last job site or job location was. This would be the address of
the place that you last worked.
Where is your job location?
A job’s location usually means where the job is performed. The vast
majority of jobs are performed in a single, specific location: a
workplace. In some cases, such as a field technician, the workplace
varies because the work involves going to various locations and
provide technical service to support a service.
What was your job site meaning?
jobsite (plural jobsites) A physical location where work is done,
especially construction work.
What is your work location?
More Definitions of Work Location Work Location means the street
address where an employee normally works. Work Location means any
fixed place of business, office, or plant where employees regularly
work in the trade or business of the employer.
So if that is correct, then the "physical location where work is done" would be, in the OP's case, their home address.
