I just went through what you are going through. It was confusing even though I was just "relearning", having been here as an author once before. It's a little confusing at first, but after you do it once, it will become clear. @drpaladin was very helpful when I was trying to get it together.
This is likely the page you were starting from: https://gayauthors.org/stories/
Use the "Add Story" tab and fill out all of the pages correctly and save. That will initiate the story. Then you have to add the first chapter as a separate step. I mention that because it confused me.
@Carlos Hazday was correct that the moderation queue usually takes a couple of days, but it can take longer, so be patient. It will be worth it in the end
