I am trying to set up my Arduino as a replacement remote control. The setup works and I can use it to turn on/off my things, for example my fan.

However, the working distance is quite short. Around a meter. The actual remote for my fan works across the distance of my apartment.

What can I do to improve the working distance of my Arduino remote? Does the LED need a back reflector or something? Does it need a different LED?

The LED I am using is this, it came in a bundle I purchased. https://www.amazon.com/dp/B07PJC7WSQ/#detail-bullets

I assume that the led you purchased just isn't as bright as the led that came with your remote. As I've seen from your link you could quite easily swap the led from the board. If the new led has the same voltage, the board should work just fine with any other led. Maybe just search for a brighter led with the same wavelength.

I don't think that a back reflector would have such a big effect to boost the range to the distance you need. Also I think it would be rather complicated to install one on the tiny board.
