Business & farm

I received a 1099-NEC Box 1 income from my recruiter.  After entering the amount, I was then asked if one of the uncommon situations applies.  It seems to me I should check the box "it is from a sporadic activity" since I did not perform a service or have a business or farm.  The recruiter is located in NY and I need to file a non-resident return for NY (my employer is based in NY).  NY asks me for the "NY source portion" of this income.  Is it  the full amount (100%) because the recruiting agency is based in NY?  Also, while this is correctly identified as a 1099-NEC Box 1 income on my NY non-resident return, somehow it comes up as a "1099-MISC Box 7" income on my NJ resident return on line 26, which asks for enclosure of document.  I reviewed the instructions for NJ return, I don't think any of the income types fit my situation (unless I consider it as a "prize/award").
