I wasted 2 hours talking to TurboTax customer support twice and getting locked out of the IRS website. Nobody told me that if I filed my 2017 late that I should enter my AGI as zero for efile. I asked the agents repeatedly if filing 2017 three months ago could be the reason? Clueless. I'm paying $80 for tax software it doesn't seem unreasonable to have competent customer support.
