Would appreciate some help on this form 1310.  Client died in 2022.  had a will & named his daughter as executor.   deceased has a refund coming.

The executor just gave me Letters of office -decedents estate naming the same daughter as independent executor since deceased house had to go thru probate. (which may or may not have any relevance to form 1310)_  Or should I ignore that and fill out part 

question is: on form 1310 should I check on part 1 b and just attach the court certificate that was dated 1-19-2023 as stating :the letters of office are now in force in the estate

or something else everytime I do this form client gets no refund for over 9 months going back and forth which boxes to mark

Thank you all for your help
