Actually, the other day I called Turbo Tax. After receiving guidance from a specialist, I was able to
e-file my taxes and they were accepted. If you do call them, please note that it is a challenge to get
past the automated system to a product specialist. They want to send you an email and have you do
the same things that have been recommended here, such as clear cache, delete cookies, etc. I just kept saying specialist and finally got one. Also, be prepared for a long call. I was on the phone for an hour.
It appears things have been resolved on the IRS end, though they have not communicated that.
