Q: Need help synching

Hi Jacqui,
 

Thank you for participating in the Apple Support Communities.
 

It sounds like you're syncing your iPod touch using iTunes for Windows but items aren't deleted from the device as you're expecting. If this is correct, make sure to follow the steps in iTunes 12 for Windows: Sync iPod, iPhone, or iPad. This article mentions the ways to delete items from your device, depending on whether you're syncing automatically or manually:
 

If you delete an automatically synced item from your iTunes library, the deleted item is removed from your device the next time you sync.
 

Remove items from your device

Make sure your device is connected, then do one of the following:

Remove an item that was synced automatically: Do any of the following, then sync your device: 

• Deselect the checkbox for the item in your iTunes library, and select “Sync only checked [items]” in the Summary pane. 

• If the item was added because it’s part of a synced playlist, remove the item from the playlist. 

• Change your sync settings to keep the item from being synced.

Remove an item that was added manually or using Autofill: Click On My Device, select an item (or items), press the Delete key, and click Delete. 

The types of content you can sync depends on your device. For more information, see the documentation for your device.

If you're using Apple Music and want to delete music from your device, see Delete songs and music videos from your iCloud Music Library.

All the best.
