Irma IRA withdrawal taxes deferred over 3 years applied to 2018 return

[fxblake]

On my 2017 return, I filed form 4684 Casualties and Thefts, as well as 8915B for my IRA withdrawal...I deferred the taxes on the withdrawal over 3 years and received a refund on the taxes withheld.  I'm now doing my 2018 taxes and don't see anywhere, nor did TT ask about, the tax due by deferring the IRA taxes.  How do I apply taxes owed over 3 years to my 2018 and then the 2019 returns?

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...
