To remove suggested playlists on Spotify, you can follow these steps:

1. Open Spotify and log into your account.
2. Go to the "Home" page.
3. Scroll down to the "Made For You" section where you'll find suggested playlists.
4. To the right of the playlist, you'll see three dots. Click on them.
5. A drop-down menu will appear. Click on "Hide this Playlist."

Unfortunately, you can't permanently remove the "Made For You" section or stop Spotify from suggesting playlists entirely. However, you can improve the suggestions by listening to more of the music you like. The more you use Spotify, the better its algorithm will understand your musical tastes.

Also, remember to "like" songs you enjoy and "dislike" songs you don't. This will help Spotify's algorithm to suggest playlists that are more in line with your preferences.
