I have found it here but since I have older phpstorm there is a way to do it easier

Step 1: Install Bitbucket Linky using this guide. Note Bitbucket Connector is no longer being developed.
Step 2: Set up a new private repository on Bitbucket. If you’re using WordPress, I’d recommend creating a repository for each plugin you are developing, rather than for the entire install. Leave it empty for now.
Step 3 Create a new project in PHPStorm or use an existing one. Click VCS>Create Git Repository. Select the path of your project.
Step 4 Now the repository is properly set up, I then added – using Finder – all of my files into the local repository folder.
Step 5 Select all of your project – which should be in red text – and click VCS>Git>Add. This will have added these files to the project, but not yet pushed them to the remote server.
Step 6 Now select the root directory of your project and click VCS>Git>Commit Directory.
Step 7 Go to VCS>Git>Remotes and add a new remote. You need to get this in Bitbucket by clicking ‘I will be starting from scratch’ and then copying the URL (https://youraccount@bitbucket.org/youraccount/yourrepo.git) and pasting it into PHPStorm.
Step 8 Click VCS>Git>Push. This actually moves the files to the server.
Hope that helps some one – took me ages to figure out. You’re now in the capable hands of many guides on how to use Git.

After step 6 I couldn’t find Remotes so I just clicked on project folder, right click, git->repository->push and then clicked on top remote and then added bitbucket link (https) and all the files were being pushed there.

That’s it.
