Hi there Stacylynn0605,
It sounds like you are concerned that you will not be able to sync your iPod Shuffle when you have iTunes Match enabled on your computer. According to this article, only iOS devices (iPod, iPad, and iPhone) are unable to sync locally when you have iTunes Match enabled:
iTunes Match on iPhone, iPad, or iPod touch
Syncing music with iTunes will be disabled while iTunes Match is enabled on your iOS device.
You should be good to sync your iPod Shuffle without any issues, unless this is a new library or computer since the last time the iPod was synced. In that case you will be prompted to delete the content on the device to sync to the new library:
Manage content manually on your iPhone, iPad, and iPod
You might see a message that your device is synced with another library. This means that you've used a different computer to sync your device in the past, and iTunes can't sync without first erasing and replacing all iTunes content on your device.
You can transfer purchases from your iPod to your library before you sync, but anything that was imported from a CD or other sources would have to be reimported to iTunes if they aren't there already:
Redownload or transfer your iTunes Store purchases from an iPhone, iPad or iPod to a computer
Thank you for using Apple Support Communities.
