行くんですか is using the “のです” grammar point. Basically (for verbs) what you do is make the verb plain form and then add “のです”. However this is almost always shortened to “んです” because it’s a million times smoother.
What this does is change it to an explanation, or if its a question, you are asking for an explanation. So basically instead of asking for a simple answer, you want more details. It’s kind of like where your wife goes “Where are you going?!” Its not a simple question ,she wants some details dammit. So i.e I’m going out to visit Joe.
Its a very common spoken style, (so usually not in writing or in casual spoken style writing). You can also apply it to adjectives and nouns, and it also comes in plain form (んだ). I don’t think Koichi has a lesson on it yet, but you can check out more details here, just go down to “Using の as an explanation”

P.s you’ll soon learn that “です” is combined with a lot of different types of statements.
