If you check the box "Entire distribution is qualified", it removes the entire distribution from taxation.  Don't think this is the way to go.  I checked the "2020 Coronovirus-related Distribution" box on the distribution W-2 and then used Form 5329.  The W-2 info auto populates to the form but, you still have to type in the amount to exclude in  the "Distributions Not Subject to Additional Tax Smart Worksheet", line L. This works and takes out the 10% tax.  I have not tried this with Form 8915E.
