I'd like to add one more suggestion... in addition to the ones already given. I agree that getting a qualified teacher is by far the best way to learn the piano. Which is kinda hypocritical for me to say, as one who is actually not in a position to have a teacher.
So if you are in the same boat as me, I would definitely second Nightowl's suggestion to work through a method book. Second best to learning from an actual teacher is probably the Youtube channel of the Let's Play Piano Methods guy. Whatever method you want to use, he will talk you through it š
When I first started learning I used his channel as well, and learned so many things I would never have thought of on my own.
