Hi, I am trying to change the filing status on my 2021 return on Turbotax Desktop, but when I try to submit I get an error saying that "Form 1040-X cannot be filed electronically if there is a change in filing status." Is that right even though I e-filed my original return? Am I also unable to e-file the amended return with California as well? If I do have to physically mail the amended return, do I also have to send copies of any attachments such as my W-2? Thanks.
