Had a part time job for a couple of weeks and I made a total net pay of $85 I do not see any state/federal tax taken.Just SS and medicare. Why no state or federal taken?

Since you made such a small amount, the employer did not withhold taxes from your pay, just the SS and Medicare.  It you have other income besides this you need to include this on your tax return.

I have two other jobs.  How do I include this 2 week gig?

You must include all income when determining if you have to file.  TurboTax lets you enter multiple W-2's.

But will I even get a W2 from this short stint job?  I already have mine for the FT job, waiting on the other.  I haven't seen anything yet for this short job.

You should.  If you don't, around 2/15, you can file with your last pay stub as a substitute W-2.

If that is all you made, then you are not required to file.  If there was any federal or state tax withheld, then I would recommend filing to recover it.  Please see the link below for filing requirements.
