Turbotax will have that credit in the NY tax section. There are several pages listing state-specific additions, subtractions and credits. Look for it there.
However, because there are so many different state issues in the different states, turbotax may have the calculations but not a lot of specific help. You may want to have the actual form and instructions handy to help you fill out the information in Turbotax. https://www.tax.ny.gov/pit/credits/historic_rehab_credit.htm
