questions with estate tax return

I just started an estate tax return with turbotax Business.  I have a few questions regarding K-1 forms, beneficiary and acquired dates with sold dates in two different tax years.  First of all, the only item with the estate were stocks with no beneficiary listed so they were transferred to the estate name and sold under the estate name.  The check was deposited in the estate checking account and then a check was made payable to the only person in the will. The will listed only one person who is also the Executor.  Would a K-1 form still need to be completed ?  Would the person listed in the will be the beneficiary even though no one was named one with the stocks ? Also, during error check, it was flagged that the acquired date was 1/5/2021 (date of death) and sold date was 1/14/2022 which was two different tax years.  Will that be an issue ?  Sorry I have many questions but any help would be greatly appreciated.
