first I create a project in the account menu and linked to a repository: Screenshot of the menu of my github account
but when I go to my repository, I found nothing.Screenshot of the project's tab on my repository
How can I merge the account project and the repository project?

It is simply at a different level, there are account level projects and repository level projects.
Say I have projects that i want build for my portfolio, say todolist. In my account I would have a project for what it is that i need to do get that underway (hire staff, make the scaffolding for the project with create-react-app, buy a computer etc). Ok now that's done... time to start adding features to the repo that you have made... so make a project in the repo... maybe the todolist needs a list? Card for that, install a test suite? All the features i (might) put into the project for a repo... the account level is before you create a repo (at least in my world).

Unfortunately, in the "New" Projects, this is currently not possible. "New" Projects is currently beta, so we will have to see what happens. https://github.com/orgs/community/discussions/52841
Reading on the difference between GitHub repositories and GitHub projects, you have correctly associated at least one repository to your newly created project.
Your profile page (
github.com/JulioMelchorPinto) does show two projects.If it should show "3", maybe you have associated to the new project a private repository.
