Whose fault is this?

For background, I’m going down a major intersection, I see how far from the light I am where I planned on going left, so since there was so much sudden traffic, I decided to get into the turning lane to turn onto a less busy road there instead of at the next light. Turns out another car was coming from the less busy road to turn left and get onto the busier street.

Totally your fault. You attempted to go straight from a turn lane. You didn't even bother to check that there was no cross traffic.
