Both parents died in 2016. Do I need to File a 1310 or any additional forms with their joint 1040 that I am completing on turbotax?

I am co-trustee on trust and POA. A home/ small investment account are the only assets. Once home is sold, a sibling will get specific amount of proceeds and I will the remainder. Who will the refund be made out to?  I have EIN but, no account under that number.
