                       if(task.isSuccessful()) {
                           for (DocumentSnapshot documentSnapshot : task.getResult()) {
                               String name = documentSnapshot.getString("Username");
                               String email = documentSnapshot.getString("Email");

Since you are using firebase authentication, then do the following:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
DocumentReference docRef = db.collection("Teacher Database").document(user.getUid());
docRef.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
    @Override
    public void onComplete(@NonNull Task<DocumentSnapshot> task) {
        if (task.isSuccessful()) {
            DocumentSnapshot document = task.getResult();
            if (document.exists()) {
                Log.d(TAG, "DocumentSnapshot data: " + document.getData());
            } else {
                Log.d(TAG, "No such document");
            }
        } else {
            Log.d(TAG, "get failed with ", task.getException());
        }
    }
});

First, get the currently logged in user, and then pass the uid as an argument to the document()
