I don't know what version of Turbotax you are using. I'm using desktop deluxe. during the interview process it asked if I had any FTC carryover to which I entered yes. then it went to a screen that allowed entry of the c/o when I previewed the return it was an official IRS form, not a PDF. however, I have not yet e-filed so I don't know if this really works.
I'm surprised no one said anything about this. from my understanding there is no way to include any PDF document with an e-filed return.
