Received two K1s from the same Limited Partnership.  These would be reported on this year's 1040, but the Decedent died in 2016.  A final 1041 was filed in 2018.  

I have the EIN and could report this to the estate.  But I'm not sure the impact given that there has already been a final 1041 filed and K1s distributed and reported on the beneficiaries' personal returns.  I'm also not sure why Decedent didn't get the K1 the last couple of years.  And, in terms of matching, this was reported to the SSN rather than the EIN.  Any advice would be appreciated.
