I have not used all 5 of my efiles in my home and business software
Maybe *YOU* haven't used the maximum of 5 e-files for your e-mail address. But that doesn't mean somebody didn't use your e-mail address to file theirs. Perhaps another family member?
The IRS (not turbotax) limits the number of returns you can e-file each year to 5 per e-mail address. So if you have another e-mail address, try it.
