Corporate Office is in NY; I am permanent WFH worker in CT; What is my allocation?

I work for a large company headquartered in NYC.  I am a permanent WFH worker living in CT.  I do not commute to NY.  The only time NY taxes were deducted from my wages was my bonus check, delivered in March.  My W2 has the same amount of wages for both NY and CT.  When I fill out my NY taxes as a non-resident, I am being asked what percentage of my work was done in NY.  The true answer is 0, because none of my work was done in NY.  But TurboTax says that 0 is not an acceptable response.  Any suggestions as to what percentage allocation I should use for NY and the justification for your answer.  Thanks in advance.
