2015 Kia Soul engine wont start, TCS light on

My 2015 Kia soul has been having an issue where the engine will shake and try to start, but just kinda hums and fizzles out. Also, after I do get the car started, the TCS light comes on and I have to accelerate super slowly or else the car feels like it will give out on me.

The battery is under a year old but I am not sure what else to look like. I know I need a spark plug changed but I'm not sure if that would be it. Any advice on where to look?
