Hello billyjess
To take a backup of your file which puts it in the zip folder you need to go to File and choose Back up, this will take you through the steps to back up your company file which will be in a zip folder you can pass onto your accountant.
I have attached a Help Article on backing up your company file here for assistance.
Did you know that instead of having to provide a copy of your file to an accountant if your file is online you can simply invite your accountant to the file and then they will be able to view it without needing to do a backup. I am also providing the Help Article on inviting your accountant to your file for if your file is online and you wish to do it this way instead.
Please let me know how you go.
