Financially Support Another Person | Grandchild

Without claiming a Grandchild as a dependent, Turbo Tax asks if the taxpayer/filer provides support for another person.

If the tax filer (Grandpa) has a Grandchild that he periodically sends money to (grandchild is attending college) to help them with living expenses, etc., should the answer to that question be Yes?   The Grandchild will be claimed as a dependent on the tax return of their parent - Grandpa is not interested in picking up a dependent on his return - just contributing to helping his Grandchild.  Is this a gift situation?  

What is the benefit of identifying the support that Grandpa gives/provides to the Grandchild?   Also, the amounts that Grandpa provides/gives are less than 50% of the total support the Grandchild receives primarily from parents. 

Thank you and Help.
