I made a frozen buttercream transfer on top of a cake and then covered the entire cake with the same buttercream. The recipe is half butter and half shortening. Do I have to keep this in the fridge?

The recipe that I use has both shortening and butter in it, and the pro that I know that uses it says that it doesn't need to be refrigerated. Did you use heavy cream in the recipe? That needs to be refrigerated.

If your fridge is cold enough, your buttercream can keep for months till you finish it. Please keep in a good tupperware container.
