When you override keyPressEvent you are listening to the events of the window, instead install an eventFilter to the QTextEdit, not to the window as you have done in your code, and check if the object passed as an argument is the QTextEdit:

def initUI(self):
    # ...
    self.text_box = QtWidgets.QTextEdit(self)
    self.text_box.installEventFilter(self)
    # ...

def eventFilter(self, obj, event):
    if event.type() == QtCore.QEvent.KeyPress and obj is self.text_box:
        if event.key() == QtCore.Qt.Key_Return and self.text_box.hasFocus():
            print('Enter pressed')
            return True
    return False

This is building upon the answer of @eyllanesc and the problem @Daniel Segal faced. Adding the correct return values as such to the eventFilter solves the problem.
