Guidance on college process - what i need to do and when!

I am a Sophmore who just completed my PSATs. From the little research I’ve done online, it seems like a lot of steps in the process to get to college admissions in Senior year! Whats a good way to know all the steps in the process and the timeline of what I should be doing and when? I just want to make sure im taking advantage of everything I can to make the application process in senior year as manageable as possible. I’m a first gen US college student so my parents are not familiar with the college process here…kind of need to do my own research to figure everything out. Anyone else out there in the same situation as me? What resources are you using?
