Textures Aren't Working Right

Okay, I’m trying to make a game and created a texture for a model in unity, but when I imported the texture and added it to a material, the whole texture was off. This is my first time trying to make a game, so of course, I have hardly any idea what I’m doing…

Does anyone have any idea where I screwed up?

Did you export the model again once creating the UV map to ensure the model is using that uv map for the texture?

So that’s where I screwed up… yeah, I guess I did everything right (I think) but never exported the model again after finishing the uv map. I just tried re exporting it and it fit on the model correctly. Thank you guys so much for the help.
