Exporting issues on computer and phone

Just to be more specific. I use premier on my Mac. The input video is 1920 1080. I set the sequence settings to 1920 1080. I edit the video. I export at 1080 HD. When I watch the video on my computer there's giant black bars on the side and on the preview icon. When I airdrop that file to my phone and open it, it's the super small zoomed out video you see in the first picture. I check the info on the exported video it also says its 1920 1080. I'm lost.
