Positionating a layout over the top of a Central Widget in Python

Question

I'm having some problems with the Central Widget, I'm trying to positionate the LabelTitle overlapping the top of the central widget, so it would look like a small box title, but for some reason I can't figure out how to stretch the space between the layout and the top of the central widget.

I tried using a Frame, or the layout.setRowStretch but it didn't work for me

class WindowEtiquette(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setFixedSize(460, 350)
        
        self._add_widgets()
        
    def _add_widgets(self):
        self.CuadroLayout = QGridLayout()
        
        #Generando elementos y layouts
        
        self.TituloLayout = QGridLayout()
        self.labelTitulo = QLabel("Formato de la dirección")
        self.labelTitulo.setObjectName("EtiquetaTitulo")
        self.TituloLayout.addWidget(self.labelTitulo, 0, 0, Qt.AlignCenter)
        
       
        self.CuadroLayout.addLayout(self.TituloLayout, 0, 0, alignment=Qt.AlignTop)   

        self.widgetCentral = QWidget()
        self.widgetCentral.setObjectName("FondoEtiqueta")
        self.widgetCentral
        
        self.widgetCentral.setLayout(self.CuadroLayout)
        self.setCentralWidget(self.widgetCentral)

The objects name are in a CSS File, and I don't add any margins or paddings in them

I know maybe I shouldn't worry too much about the GUI, but I wanted to see if I could solve that problem

Your code doesn't match the screenshot, please [edit] your post with the current code, so that we can understand what's wrong with it. Be careful with the [formatting](https://meta.stackoverflow.com/a/251362) (check the post preview before submitting). — musicamante, Jan 27 '22 at 19:51

I'm sorry, I am kind of new in this place so I guess I jumped over conclusions, I'm sorry if the code it's too big, I was in kind of a rush doing it so I just did a mess, but here it is:

class VentanaEtiqueta(QMainWindow):
    def __init__(self):
        #Valores iniciales de la ventana
        super().__init__()
        self.setFixedSize(460, 340)
        
        #Función de generar elementos
        self._agregar_Componentes()
        
    def _agregar_Componentes(self):

        self.TituloLayout = QGridLayout()
        self.labelTitulo = QLabel("Formato de la dirección")
