Hi, I run a youtube channel since I was 17, and l've had it under my grandfathers name, as l was a minor.I haven't gone around to change it to my name until this year. My question is though, since he receives the form under his name, he would file the taxes under his name correct? I receive the money however, so do I have to pay taxes for it, or not? I'm really lost and nobody has ever taught me a thing about taxes. (I do pay him the money that is due from taxes)

I was informed from the r/tax subreddit this is considered fraud and I hope I won't be in trouble for this. Is it possible for youtube to change all the prior tax forms I received ? I'm so lost and feel like an idiot
