Paying tax on profits from a YouTube channel for 2020 - how to do it right?

Question

YouTube

Until April 30, you will need to hand over 3-personal income tax for income received in 2020.
And last year, from my YouTube channel, I received only $105 from Google)))
And I understand that I must indicate this amount in 3-personal income tax and pay 13% of $105 - or not?
And if so, in what form should it be indicated there in 3-personal income tax and how to calculate income tax?

ps: I tried to search for information on this topic - I have not seen a more confusing and ambiguous topic lately - nothing is clear to be honest )))

Not advertising, I don’t really like it at all, but Konoden made several videos about it on his YouTube channel.
