More information may help resolve your issue. For example, did you include your full salary before the 401(k) contribution made by you as an employee as a deduction on your Form 1120S tax return?  Did you report the 401(k) contribution you made in box 12 of your W-2 from the S Corp?

 

As a shareholder, your S Corp isn't allowed to contribute to your 401(k).  Instead, the contribution to the 401(k) must be made from your W-2 wages paid by the S Corp.
