I never got help, followed all the steps to amend the return, and mailed them both to each proper address (it's different for amendments) with a short explanation. I had to request permission from the state of California to mail it instead of e-file first. Of course, an amendment to our corporation and the K-1 also meant an amendment to our personal taxes (because they had been filed already). So I mailed them all separately. I only received confirmation about our personal tax amendment, the gov't never said anything about the business amendment.
