Income tax on income from inherited shares and fds

Dear friends and professionals,

I am person of Indian origin with foreign citizenship. Have a PIO card and PAN card. In year 2017, I have inherited funds from FDs and a DMAT account . Bank has trasmitted these accounts under my name based on nomination from my deceased mother. These assetts are part of my deceased father's Estate where I am the legattee in his Last Will.  My mother was life interest beneficiary and was receiving income from these accounts for 13 years. My father's Will  is in process of Probate in the Court.

(1) As these funds are in my individual name now and bank is deducting TDS on interest and dividend income...what kind of income tax paperwork i am required to file and when ? 

Thank you.
