1099-What?

Which box #?

Did the client tell you that both forms don't apply; that only one is the correct amount?

If this is for reportable income, are you already reporting more than that total?

Which form are you preparing?

Or, are you handling the issuance of the 1099-XXX on behalf of a client that issued these to others?

More details are always helpful.

Having two 1099s from the same entity isn't always an error.
