Please provide a reproducible code example.

Use one of the example data sets for whatever GARCH package you are 
using, and tell us what package that is, and comment your example so we 
can tell what you're doing.

You haven't given us enough information to say where you'll find the 
p-values, since among other things you haven't even told us which of the 
many GARCH functions within R you're using.
