How do I upload my w-2’s without an import code?

You can key a W-2 in by hand.  It is pretty easy.

And….SAVE YOUR OWN W-2!  TURBOTAX DOES NOT SAVE IT FOR YOU.  TurboTax will not have a copy of it in your account and will not have an image even if you snapped a photo or imported it.  It is up to you to save it for your own records as stated on the back of the W-2. 

If you don't have a direct import code from your employer, you will need to upload a picture of it or type it in manually.
