Form 14039 not Final?

Can't e-file as above form NOT updated yet? I signed up for email alert when available and was notified but update is not ... well ... updating. Did this several times over past week. I want to e file as my 2020 AGI is WAY down from 2019 (disqualifying me from any further stimulus check). 

1. can I file form 14039 by mail and e-file my returns?

2. What is ramification of deleting form 14039 on IRS if I have already filed report with FCC and frozen all my credit files?
