1099, 1096 e file authorization

[SunTaxMan]

In a Gear Up seminar, instructor suggested using 8879 for 1099 - just leave all of the dollar amounts zero. I have been doing that with just a "watermark" for "Form 1099" or "Form W-2"

But....... someone, somewhere in the last several days advised a specific form number for 1099 efile authorization. I don't remember the form # and cannot find it in the program. (old age setting in?)

Anyone help with this?

Thanks,
