Many things going on here Eh?  You should call executor and get EIN for estate as that is public information and has to be entered.

Box 14 info is mostly cosmetic and adjusts basis or provides other info.  It does not show losses by the estate.  And basis is usually not needed to be tracked in inheritenance cases.

Is the K1 for 2021 or 2022.  And is it final.  Kinda late in year for getting a calendar year K1 from an estate.
