First off, discount "watching TV" as study in poker. Poker shows are not teaching tools. The hands they show are usually selected for maximum activity to provide better entertainment. Even if that weren't the case, a correct decision made by them will likely be incorrect in a micro/low-limit game.
I'm not familiar with poker podcasts or Youtube instructionals, so I can't speak to them.
Personally, my main source of education (outside of playing) was from books. "The Theory of Poker" is still a great resource.
But I would conclude like this: if you feel you have a good sense of the fundamentals, the large majority of your study time should be analyzing hands you've played. After each session, go back and look at all the hands in which you were actively involved. Then critically analyze every decision on every street of every hand. When you are unsure about your play, post here and ask for some feedback.
Outside of active play time, 75%-85% should be analyzing the hands you played. The rest should be reading articles, books, forums, etc, and watching quality videos and podcasts relevant for your level of play.
Hope this helps.
