I am on disability and have been for over 30 years. My wife has a business.

You are asking how to get out of something and I don't know what you are "in to." If an argument can be made, by SSA, that you are working in your wife's business, this is something that requires prompt attention.  I would suggest contacting a C.P.A. concerning procedures to request that the 1099 be re-issued, or how the income can or should be reported on a tax return, preferably under your wife's business. Because a 1099 was issued does not mean that you worked.  However, you are smart to ask now, and I would recommend contacting a local attorney in the Social Security Disability area and have them help you report, as soon as possible, what happened.  You have a duty to report to SSA if you work, and far better for you to have something in writing explaining the "appearance" that you worked than being in a position to explain what happened when SSA asks.
