Form 1041 Question

Dad died in 2019

we sold his house last year for the value of the house at the time of his death so our gain was zero.

we sold the remainder of his stock and $9k was reported to the IRS

we had funeral expenses of $7,000, legal fees of $6,000 and we paid the real estate broker $13,200

do we even need to file a final estate tax return?

 

As an aside does anyone know what "Non-Covered Securities Transactions for which basis is not reported to the IRS" means in box 5 of "Form 1099-B  Proceeds From Broker And Barter Exchange Transactions"
