Inheritance of fds and saving accounts

Hi
My maternal grandfather demised on 7.8 18.
His assets are transferred to my maternal uncle but fixed deposits in his name still continue in his name as fds have not matured.
Do I have to show fds in grandfather's account? or do I have to transfer it to my uncle's account as on 31.3.19?
Also let me know what treatment do I have to do with savings account?
