How soon will 2018 w2s show on your site

[DoninGA]

That is dependent on the TurboTax partners who provide the W-2's.  The forms are usually available for import around the end of January or early February.  Your employer is required to provide you with a copy of a 2018 W-2 on or before January 31, 2019.
