Can anyone help me find my twitch video? I want to download and edit it ...

I streamed it on twitch with my username KRAZYKOOLKIDS2017 and the video title was Halfdozen2013 infinite warfare, but it's like gone? This is my first day ever using twitch. Can someone please help me. I looked online and it says share to YouTube. I connected my YouTube but the video isn't showing up on twitch. Can I just download it to my computer? Trying to download it so I can use Sony Vegas pro to edit it but it vanished lol. Please help
