File rejected- saying my SSN and last name does not match the IRS records- after checking- it does match my IRS records. Second year this is happening

When filing last year- both my federal and state return were rejected- stating that the SSN and Last name did not match IRS records. I signed on the my account on IRS website and my SSN and last name were correct. I was able to file my 2017 Federal, but was told to send my State by mail- which I did, but never received.

Now filing for 2018, I am getting rejected for the same reasons.
