If the estate received the proceeds and they were deposited in the estate account (presumably with an account that bears the EIN of the estate), then a Form 1041 for the estate should be filed that includes the sales transaction.
If the estate sold the house at a loss, and the property was held for investment purposes or rental use (e.g., a beneficiary did not reside in the house), then the loss could be distributed (passed through) to the beneficiaries on the K-1s generated by preparing Form 1041.
