Minecraft account is not signed up?

I'm incredibly sure that I entered my data correctly, I took care of everything and even saved the password (which I created) on my computer, nevertheless I'm told that the email or password is incorrect, which, as I said, is wrong can be.

Then I would go to your account at Mojang. There you can see whether another email address is registered there.

Or you click on "Forgot your password?" and send you a new one, then you will see if it reaches the email address you used and you can create one again and try it
