From your description of the business, it REALLY should NOT be a corporation. Is there a reason why you wanted it to be a corporation rather than a Sole Proprietorship?
I REALLY recommend having a GOOD tax professional do the corporation return (some who does lots of corporations), and analyze if the corporation is a good idea. Again, from your description, it doesn't sound like a good idea.
And the fact that you filed your personal tax return BEFORE the corporation shows that you don't know how things work. The corporation needs to be filed first, and that will affect your personal tax return. So you will need to amend your personal tax return. And I hope you filed an extension for the corporation, otherwise you already owe quite a bit in late penalties.
