I would disagree with the others here and say that jumping the gun isn't necessarily always a bad idea. I think of it as a useful tool to be used sparingly for exploration.
I can see why you would try to attempt a Chopin etude upfront, as I would do the same. I would do it to know whether it's possible or not, personally speaking.
I would expect your current playing of the wrong note etude to suit the name of the piece more than the composer intended. There is nothing wrong with that -- you would be a one in a million talent if it were otherwise.
However, now I think it would be better for you to go back to easier pieces and see if your work on the etude has made them easier to learn. If so, that is well and good. If not, that is a red flag -- it would mean that you have essentially "crammed" one piece, but not learned much.
