Replying to Mixing In a Cell Phone Video? What do I do? Premiere

This is probably easy but before anyone says google, can somebody tell me or point me in the right direction. Google keeps telling me how to edit sweet videos on my phone, how to turn a vertical video to a horizontal one etc.

I don't edit very much at all, and have never mixed a video from a phone into a project. Using Adobe Premiere. I don't care if the quality isn't as good at that size as the rest of the video, I just want it in.



Any help would be awesome.
