Form 8915-F, Qualified Disaster Retirement Plan Distributions and Repayments is providing invalid information for a Coronavirus-related distribution. Any ETA on a fix?

Took a Coronavirus-related distribution in 2020.  TurboTax is filling in the wrong line (C) on form 8915-F.  Only line D should be used.  I followed TurboTax's recommended fix but it doesn't work.  I can't find any other way of overriding this.  Any ideas?  Has this already been identified as a bug?
