Unfortunately, when I filed my extension using TurboTax business, I also e-filed my return with the form 7004. I misunderstood the program's instructions, which told me that Massachusetts required e-filing of returns. So I mailed the federal form 7004 to the address the program gave, and I also e-filed both my federal and Massachusetts tax forms with the 7004 attached to both. Now when I try to e-file my return with the information that I need the extension to wait for, the program tells me I have already e-filed my return. How do I fix this?
