Still works on 2019.3! I just had to change a few things to work with TMP_InputField.

the best way i found is to subclass InputField. You can look into the source for the UnityUI on bitbucket. In that subclass you can access the protected m_keyboard field and check whether done was pressed AND not canceled, that will give you the desired result. Using "submit" of the EventSystem doesn't work properly. Even nicer when you integrate it into the Unity EventSystem.

Something like this: SubmitInputField.cs

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine.Events;
using System;
using UnityEngine.EventSystems;
using UnityEngine.Serialization;

public class SubmitInputField : InputField
{
    [Serializable]
    public class KeyboardDoneEvent : UnityEvent{}

    [SerializeField]
    private KeyboardDoneEvent m_keyboardDone = new KeyboardDoneEvent ();

    public KeyboardDoneEvent onKeyboardDone {
        get { return m_keyboardDone; }
        set { m_keyboardDone = value; }
    }

    void Update ()
    {
        if (m_Keyboard != null && m_Keyboard.done && !m_Keyboard.wasCanceled) {
            m_keyboardDone.Invoke ();
        }
    }
}

Editor/SubmitInputFieldEditor.cs

using UnityEngine;
using System.Collections;
using UnityEditor;
using UnityEngine.UI;
using UnityEditor.UI;

[CustomEditor (typeof(SubmitInputField), true)]
[CanEditMultipleObjects]
public class SubmitInputFieldEditor : InputFieldEditor
{
    SerializedProperty m_KeyboardDoneProperty;
    SerializedProperty m_TextComponent;

    protected override void OnEnable ()
    {
        base.OnEnable ();
        m_KeyboardDoneProperty = serializedObject.FindProperty ("m_keyboardDone");
        m_TextComponent = serializedObject.FindProperty ("m_TextComponent");
    }


    public override void OnInspectorGUI ()
    {
        base.OnInspectorGUI ();
        EditorGUI.BeginDisabledGroup (m_TextComponent == null || m_TextComponent.objectReferenceValue == null);

        EditorGUILayout.Space ();

        serializedObject.Update ();
        EditorGUILayout.PropertyField (m_KeyboardDoneProperty);
        serializedObject.ApplyModifiedProperties ();

        EditorGUI.EndDisabledGroup ();
        serializedObject.ApplyModifiedProperties ();
    }
}

You should be able to achieve the same by using this:

function Update () {
        Event e = Event.currrent;
        if (e.type == EventType.keyDown && e.keyCode == KeyCode.Return)
            //Put in what you want here
    }
