I'm waiting on 2018 8915B myself for Irma-deferred income from 2017. According to the TurboTax support forum, "The 8915B (and all of its programming and testing) is scheduled to be available in TurboTax on 2/28/2019." You can find the form/programming availability update dates here: https://care-cdn.prodsupportsite.a.intuit.com/forms-availability/turbotax_fed_windows_individual.htm...
