Sure, here are the steps to remove your podcast from Apple Podcasts:

1. Open iTunes on your computer.
2. From the menu bar at the top of the iTunes window, choose "Podcasts".
3. Go to the iTunes Store by clicking on the "iTunes Store" button on the top right.
4. In the iTunes Store, click on "Podcasts" in the navigation bar at the top.
5. Click on "Submit a Podcast".
6. In the "Podcast Feed URL" field, enter the URL for your podcast.
7. Click "Submit".
8. You'll be asked to sign in with your Apple ID. If you don't have an Apple ID, you'll need to create one.
9. After you sign in, you'll see a message that your podcast has been submitted and is under review. You'll receive an email from Apple when your podcast is approved.
10. Once your podcast is approved, it will appear in the iTunes Store. To remove it, you'll need to contact Apple Podcasts Support and request for it to be taken down.

Remember, removing your podcast from Apple Podcasts means it will no longer be available for download or streaming from the iTunes Store. If you want to make your podcast available again in the future, you'll need to resubmit it.
