Business & farm

I listed my business as a partnership when it should have been listed as an S-Corp.

Your use of the words "MY business" indicates to me that you are the sole owner of the business. If this is the case, then in no way, form or fashion can it be or have been a partnership. So first, "exactly" where did you list this business as a partnership? On some past tax return you already filed?  When you registered the business with the state? If so, which state? On an IRS Form 2553 that you already sent to the IRS? Something else?
