It turns out Telegram defaults to storing media on your phone. It is very easy to fix. Instructions are here:

Thank you fren. You reminded me to delete that app from my phone. I can't stand the interface. I kept meaning to but your post inspired me.
The only reason I am using Telegram is because there is important content there that is not available anywhere else. It's amazing what credible info I have found out there that would have been banned anywhere else.
The format is not ideal. It's relatively frictionless for me now but it took some getting used to.
