Can light at the entrance of the courtyard but lit in the window

I live in a private apartment, and the entrance to the house is right on the main street. Last year, the rabbi told me that in my case, according to all opinions, it is preferable to light at the entrance of the house rather than in the window. However, this year I forgot and lit in the window as I was always accustomed to, and immediately after lighting, I remembered that in my case, where there is an option at the entrance of the house, which is also the entrance to the courtyard, I am obligated to light at the entrance and not in the window. Therefore, I am asking whether I have fulfilled the obligation retrospectively, or do I need to light again?
