All jobs will have x% of nonsense and y% of what you actually really enjoy doing, and I think as long as y >= 10% then you'll do okay.
Honestly, I like sitting by myself and grappling with tech problems. It's nice that I'm allowed to sit inside my own head and think all day. Maybe it's because I'm young enough that the problems I'm facing still seem somewhat novel. But perhaps it's true that OP is more extroverted and doesn't enjoy that nearly as much.
Good on them for finding a better career fit. If I had to interact with people all day, I would die.
I have some bad news for you. As you become a more senior developer you will spend most of your time interacting with people, and a lot less time just "sitting and thinking".
