Hi there,
I don't have a definite solution but wanted to share I got the same rejection email. When I logged in and did a review it says the State was rejected because the Federal that it's linked with hasn't been accepted yet. I think the IRS Federal are delayed this year and only opened on 2/12. In the past my federal was always accepted within days of filing so I'm hoping this is an easy fix and once my federal is accepted we can efile State again.
Keep you posted if anything changes.
