How can I learn to properly research stocks?

I’m relatively new to stocks, about 5 months, since I only recently became old enough to open a TFSA. Right now most of my research is through YouTube, ChatGPT, and sometimes Twitter and Reddit. I feel like this way sucks for actual and factual information because it feels like everyone is giving false information, making things seem bigger/smaller, or trying to sell a course.

I want to go beyond surface-level info and actually be able to analyze a company properly. I’m currently tracking a few stocks and ETFs, and I want to improve how I evaluate them instead of just relying on hype or social media.

I tried to do some research on stocks but I don't understand what to look for and what is a good or bad sign. I like getting information through reading books so I ordered One Up On Wall Street by Peter Lynch, and The Five Rules for Successful Stock Investing by Pat Dorsey, which are arriving in a week or so. I also made a doc where I write down things about the company I'm interested in like What they do, their Market Cap, the P/E ratio, etc. I'm also trying to learn how to read 8-K and 10-K/10-Q forms but I'm just not sure what I'm supposed to be looking for.

If anyone has some advice, or ways for how you research a stock, I’d really appreciate it.
