This just happened to me. In 2018, when I filed my 2017 married filing jointly taxes, I entered my wife's ITIN and her identifier. In 2018, she received her new SSN. Now that I filed my 2018 married filing jointly taxes, TurboTax automatically pulled her 2017 AGI/PIN (linked to her ITIN), so I got the same rejection as above (I entered her SSN as her identifier in our 2018 married filing jointly taxes).
When TurboTax attempted to fix this problem, I entered $0 as her 2017 AGI, and it worked. My 2018 taxes were accepted.
