My recent paper on arxiv does not appear in my google scholar account?
The linked question is related, but not exactly the same -- in that question, the problem is an article showing up on your profile but not listing the right venue, whereas here, the problem is that the the article does not show up on your profile at all.

In your case, the solution is much simpler: just go to your profile, click the + button, "add articles", and search the article and select it. You don't have to upload a manual citation; Google scholar allows you to associate any article with your name that you want.
