TurboTax is aware of this issue and is currently working on a solution.

As a workaround, you can answer "no" to the question "Was this a Qualified Disaster Distribution?"  and when asked "What type of disaster affected you in 2017?" leave the selection blank and hit continue.  This will not affect any calculations and you will be able to E-file.
