I want to know the answer to the following question:
In what edition was there a Refutation of Idealism?
All the background I'm provided with is that "The 2nd edition (1787) contained a Refutation of Idealism to distinguish his transcendental idealism from Descartes's Sceptical Idealism and Berkeley's anti-realist strain of Subjective Idealism.". Is that enough to answer the question?
Answer: yes
