How much should it cost to add an entry from the garage into the house?
It will depend on the material of the wall,
if your garage has a cinder block then it is a fire wall and you will need a fire rated door with self closing on it,
If it is drywall only then you can use any door even with glass in it and the design in the glass can change the price,
in any case you should consider a few thousands for it,
