I have a zip drive I want to move to my Itunes. How can I do that?

If you mean a USB flash drive, copy the files to your computer, and then add them to your iTunes library per one of the following methods:

Import music from a computer to Music on Mac - Apple Support

Import media from a computer to iTunes on PC - Apple Support (SA)

(If you literally mean a zip drive, you will need an adapter since the technology is obsolete.)

Drag the song files in it to the iTunes application window or the Automatically Add to iTunes folder.
