Has this issue been solved, or does Turbotax just not work properly for Nova Scotian residents? 

This tax credit is valid "https://novascotia.ca/finance/en/home/taxation/tax101/personalincometax/childrens-sports-arts-refund..."

I live in nova scotia, but there is no option for this in Turbotax. these are the only options that show up.

@whynotworking You have to answer Yes, then click Continue. Then select a dependant and click on "Enter Dependant Credits". Then check off "Children's sports and arts tax credit (provincial credit only)" and click Continue until you get to that credit.
