How do I learn to play piano without having to look at the piano keys?

I have been playing piano for a little over a year now, and play really well by ear, but when it comes to playing from sheet music, I can’t keep my eyes just on the music. I have to constantly look down to find where my fingers are and then I lose my place. Is there a trick to being able to jump around over the keys and not getting lost? Or is it just a lot of practice?

Whats the best way to learn play piano for free?

I’m 15, and from what others tell me, a talented composer.
I can already write good music, and read MIDI maps, but i cant read traditional sheet music or play the piano by notes or ear.
where can i go to learn how to play the piano well for free?
