googled "IT-203F B line 15" found this taxslayer support direction for filling this this schedule
https://support.taxslayer.com/hc/en-us/articles/17007711405965-How-do-I-complete-the-New-York-Income...
Section "Allocating the income" bullet 3 explain work from home for non NY residents.
====
Enter the total number of days worked at home
- Days worked at home are considered New York workdays only if the employee’s assigned
or primary work location is at an established office or other bona fide place of business of the employer in New York State.
- If the employee’s assigned or primary work location is at an established office or other bona fide place of business of the employer outside New York State, then any normal workday worked at home would be treated as a day worked outside New York State

Found no clarification like this in the following
- NYS's IT-203-F Sched B instructions
- NYS's RSU and NY workday tax code explanations
- Any legal cases stating this
Maybe this is just taxslayer clarification for questions they have received from customers. Of course they will not be liable for correctness for using it to file in TurboTax 🙂 So I guess it will be individual's decision on trusting this interpretation as defense against an audit.
taxslayer's explanation does lower NYS taxes in my case.
