Voting help?

So I’m pretty young and this is my first time voting. I was caught up in midterms for school to be able to early vote but im planning on voting on Nov 3 this tuesday. I put my location on a polling place near Brookhaven area and found three locations near me, one is really close in a church. Do i just go in on tuesday and bring my ID and mask? Or is voting in different places? I’m pretty lost, how long does it take to vote?
