The answer to your question depends heavily on how you learn. There are hundreds of books on how to write fiction. Podcasts, blogs, and YouTube videos round out the resources. As a retired engineer, I like lots of structure and, thus, focus on outlining, planning, and world building. Others, and from the contents of your question you might be one of them, write into the darkness. Then they revise, revise, and revise again until what is left meets their standards of excellence.
I am pretty sure that every writer, successful or just hoping for success, goes about their craft in a way that is their own. If it works, just keep doing it.
Because of that wide variation, I hesitate to impose my particular world view on your process. But I will offer three suggestions:
First, look for resources that deal with "story structure" for works of fiction. Sample them. Do not fasten onto the first resource that you come to. There are many theories, often contradictory. Keep looking until you find one (or a set of) resources that makes sense to you. Try it out. Adapt it to your needs.
Second, go back to those books that you have read that stayed with you over the years. Read them again. Apply some of the story structure ideas to what you have read. Try to understand what the authors of these books are doing that makes you like them so much.
Finally, keep writing. Everyday. Most of it will be less than stellar, but that is true of most creative activities. But, some of it will stand out. Learn how to tell the difference. Reflect on what you did as a writer that made a difference. Learn from everything that you do, no matter how painful the process may be.
