Non resident NYC employee side income and form NYC 1127

Hi. I'm a resident of NJ who has a side business that I conduct on the weekends on my own time--mowing lawns/walking dogs, etc. Is that side income unrelated to my NYC government employment also subject to the NYC 1127 waiver tax? In other words, when calculating what I owe on the 1127 tax form, is my income from another state unrelated to my City employment subject to the tax? I ask because Turbo Tax has lumped my non City income earned in NJ (from my self employment business) with my NYC earned income. Thank you!
