Form 8915-E is used for one Disaster year (2020) for one Tax year (2020). That's all. That means 2020 filing, and 2020 amendments. That's all.

Did you follow the link I provided, for the details? I put this one in Tax Talk:

https://proconnect.intuit.com/community/tax-talk/discussion/form-8915-e-will-now-be-8915-f/01/186194...

It is too soon for anything to have transferred. Form 8915-F, as of right now, is listed by Intuit as expected to be finalized March 17.
