I found this posted by proseries.  Evidently it will not carryover 2020 info from 8915-E.  A further issue is that there is no way to search thru the 2020 returns to find who this affects without opening each one.  Very frustrating.  I asked that a query be set up but evidently not enough accountants have shown interest in this.  

Currently the 8915-F is still in development and not yet available in ProSeries 2021. Once Form 8915-F is available carryover amounts will need to be manually entered from the 2020 8915-E. For the most up to date information on the 8915-F status see ProSeries Release Dates.
