Net losses from the estate cannot be passed through to the beneficiaries until the estate is closed and the final return is filed. Assets (aka principal or corpus) can be distributed to beneficiaries without having any adverse impact on losses incurred by the estate.
You do not have to issue K-1s if there have been no distributions that have an impact on income, gains, credits, et al (i.e., if they would otherwise be blank).
