When I rotate a video for Instagram Story/IGTV black bars appear.

Hello,

So I am very familiar with Premiere Pro.
I have created a video sequence 1920X1080p fps 23.976 with a pixel aspect of NTSC .9091(footage capture 1920X1080 fps 120 on Sony a6500. Also footage modified to match sequence fps). I did this because the footage was originally made for Instagram post, but I also thought since its longer than a minute I could make an IGTV post out of this. So I made a new sequence and changed the frame size to 1080X1920. Then I put my footage on the timeline and rotate it 90 degrees and black bars appear on the top and bottom part. Which doesn't make sense to me because they were there on the original timeline. Does anyone have an answer?

I'm not understanding why you changed PAR to .9091 in the first place, and that might be the source of your current problem. If you set the PAR back to 1.0, does this go away?

So I did this because the PAR 1.0 created black bars for me even when I recorded vertically and the PAR .9091 didnt. But even when I try PAR 1.0 in this situation nothing changes between the 1.0 and .9091 according to height.

This is incorrect: it does not matter if its 1920x1080 or 1080x1920  or rotated the PAR is always 1.0.

After correctly configuring the sequence, PAR 1.0, in the export panel it also shows the black bars.

Exactly which is my question how do I get rid of those black bars? I understand I am doing something wrong when converting it from horizontal to vertical even though in my head it doesn't make sense

You need to set up a vertical sequence from the beginning.
