Texture being imported extremely low-res

I have recently started playing around with proper models in Unity and have come across the problem of my textures not importing correctly. Textures that look crisp with normal maps and specularity in blender look like there has been a 4-inch sheet of blurry plastic got slapped on top of them and don't reflect light correctly and smudge up the texture beyond recognition in unity.

All of the answers I found are from 4 years ago and I cannot find the same menus that fixed the problems for people on the older versions. If anyone has a solution I would be eternally grateful.
