I put in a new display and now there’s white circles where I screwed

I put an new display on my iPhone 7 and I stripped a few screws and finally got them out. I bought a bunch of replacement screws and I think I put the longer screws in. As a result the screws come through the screen! Is there a easier fix for this than changing the whole dang screen?!! If you look closely you can see little white circles. I believe the screw was too long or too right is there like a filler of some black stuff I can inject in it to hide it? I’m trying refurbish the phone and sell it.
