Yes I filed I did not realize until the next day I thought my paycore website gave us are 2016 returns but it was 2015

You have to wait until at least Jan 23 to see if the IRS accepts or rejects.

If rejected, you can fix everything and resubmit. If accepted, you must wait until the IS priocesses it, and then file a 2016 amended return by mail. Amended returns take about 4 months to process.
