@JosephF8 I found the non-resident filing form for NY (Form IT 203) and it gives me the option to give an EXACT amount. Apparently the percentage/days based allocation is only for people who do not have exact amounts given to them by their employer.
Why isn't there a place in the Turbotax software to add an exact amount. And if you use the percentage option, TurboTax prompts you to fill out another form to verify the allocation you estimated is correct. This would be completely unnecessary for me since I have an exact amount. :(
