Narrative:

At approximately 10 miles sse of the ZZZ airport, I was instructing a student, and asked the student to do a number of steep turns for practice. All of a sudden we noticed 2 F15's come close to us. We stopped our flight training and immediately headed wnw toward the ZZZ1 airport. Unknown to us, we had strayed into a 'temporary flight restr area' as stated in a NOTAM. In any case, ZZZ tower advised for us to land immediately. I informed ZZZ that we couldn't land as we were a floatplane without wheels, but would land at ZZZ2 airport. A large group of officials were there to meet us. I apologized to all of them and told them I was unaware of the temperature flight restr and would never have violated the restr hand I known of it.
