If you have a C corporation that files Form 1120, you only report compensation (including wages, bonuses, and taxable fringe benefits), dividends, and other taxable distributions received. The corporation itself pays tax on its profits.

The amount reported on Schedule E is taken from Schedule K-1 issued to you by the S corporation.
