Filing ITR

My grandmother gifted me cash Rs 14 Lacs in September 2017. I invested this amount in Post office RD and TD account. Interest on RD and TD account is payable anually in September. So for year 2017-18, I have following income-
1. Interest on FD account which is less than Rs 10000, on which no TDS is deducted.
2. Cash gift received from my grandmother.
As my Total Income does not exceed MANCT, is there any specific disclosure required in any of the ITR for gift received from relative? Whether I have to file ITR for AY 2018-19?
Please suggest other Tax implications.
