                $form = $this->createFormBuilder($mensagem_default)

                //Adiciona o campo botão enviar dados
                ->add('send', SubmitType::class, [
                     'attr'=>['class' => 'btn btn-primary']
                ])
                ->getForm();

                // Renderiza os arreio para a página principal e Renderiza o formulario para o body
                return $this -> render('contactus.html.twig', ['page'=> 'contactus', 'form'=> $form ->createView(),]);
                }

It looks like you are using bootstrap. If so, you can add a bootstrap utility class for padding .p-1 .p-2 .p-3 . But, what I think you really want is a margin above the button, for that you can use .mt-1 , I have had problems with the .mt- classes and usually end up using .m-1 combined with .ml-0 to keep the left margin at zero. See here for reference.

->add('send', SubmitType::class, [
    'attr'=>['class' => 'btn btn-primary m-1 ml-0']
])

Alternatively, you should also be able to add an inline style declaration like so:

->add('send', SubmitType::class, [
    'attr'=>[
        'class' => 'btn btn-primary',
        'style' => 'margin-top:1em;',
    ]
])

You can also use customized form rendering in your template, see How to Customize Form Rendering
