Backup Using Time Machine to External Hard Drive

I am unable to backup my MAC with 120GB hard drive to a completely empty 1TB external hard drive. The message I receive is "Time Machine could not create a local snapshot to back up from because there was insufficient free space on the source volume(s)." How do I solve this issue? Thank you so much!

MacBook Air 13", macOS 10.13

It sounds like your internal hard drive is too full and you need to free up space.
