Schedule K-26 is a Kansas State income tax form, not an IRS form. Your best option is to wait for the state to request this form from you. Waiting avoids having to mail it twice (once now and again when they ask for it). You don't need to send anything to the IRS if you have already e-filed your federal income tax return.
