Transcribing a youtube video I uploaded

I gathered information from various instructional videos and put together my own compiled work. I uploaded the video to youtube on one of my channels. Now I want to download the transcription. I can not find where I need to click to do that. Now, since I own the channel, I can edit settings accordingly but I can not find where to do that either. Here is the link as a reference:

Maybe there is a software tool you can recommend that will produce a transcript of a video or mp4 file.

At the same time, someone had informed me that, yes, on youtube, on the link I provided above, he was able to view the transcription of the video. I looked around and I could not find it.
