When will the IRS Instructions for disaster (covid 19) distributions be available? Does anyone have a ballpark idea?

Unfortunately, no. You can't rush the IRS.

Form 8915 -E is not yet finalized by the IRS.

At this point and time the Form 8915-E (Qualified 2020 Disaster Retirement

Plan Distributions and Repayments (Use for Coronavirus-Related Distributions)) is not finalized. We currently do not have an estimated date when the form is ready.

Please sign-up here and we will email you once the form is live.

This is an early release draft of an IRS tax form, instructions, or publication, which the IRS is providing for your information. Do not file draft forms and do not rely on draft forms, instructions, and publications for filing. We do not release draft forms until we believe we have incorporated all changes.

At least for the 10% penalty part....

"The 8915-E Form is projected to be e-fileable starting 02/24/2021"
