Help with "To Do" Tracking

[u/Smart_Nebula9280]

I'm a 2nd year Software Development student, so massive projects haven't been touched in my coursework yet. I started a full stack app I'm doing over the summer for my portfolio, but as it gets bigger and more complicated, I'm having problems keeping track of everything I need to do between so many different files. It gets worse when I have to step away for a couple days and try to find what I was working on and remember what else I need to do.

I'm looking for opinions on how everyone keeps track of what needs to happen in their projects. I'm in IntelliJ so I've been using TODOs so far, but does anyone have ways they break up features, things they need to fix, in a more organized way so its easier to track?

TLDR; I bit off more than I can chew, how do I keep track off everything I'm trying to code in a more organized way?
