I backed up my old phone that I traded in onto my new phone. My question is can I now erase it off my new device as it’s taking up a lot of storage? I just don’t want to lose anything.

Sorry, but your question does not make sense as written.
Backing up a device puts a copy of the dat either on your computer or in iCloud.
You can not back up one phone to another. You can transfer the data from your old phone to the new one.
You can restore a backup you made of one device to another device.
If you transferred the data from your old device to the new one, then traded in the old device, and you erase the data from the new one, the data is gone.
