"if you read the 8915-F instructions on the draft pages it states do not use 8915-F for 2020 distributions to use the 8915-E for those distributions."

You have this backwards.

Separately evaluate which Disaster Year and which Tax Year.

A 2020 disaster, reporting or amending for 2020 tax year, is the only use of Form 8915-E.

-D is the ongoing form for 2019 Disasters.

-C is the ongoing form for 2018 Disasters.

-F is to be used for Disasters from 2020 and forward, for tax years 2021 and forward.
