I taught myself in a rudimentary by using alfreds piano books. WHile you look for help, my suggestion would be to spend a lot of time on basic songs while memorizing the keys (ABCDEFG) and placing your fingers on them without looking down at the keyboard (you need to train yourself to read the music while your fingers work unassisted) and recognizing the corresponding notes on music sheets. It is hard for us 30 plusers bc our mind is just not as mailable but with time and effort you will carve the neural pathways required. It just takes patience and consistency.
