Hi. You're going to need Jira administrator access to do this yourself, or otherwise speak to your Jira admin. They will be able to create a custom issue type that will be associated to your project, with screens (Create, Edit), and any standard Jira fields, plus custom fields you need. It's not difficult but has many steps and too many to list here I'm afraid. IF you do have Jira admin access and want to try creating a custom issue type, screen and fields, I recommend using the Atlassian community board - it's a great place to learn about using Jira products: Atlassian Community
