Fy2018-19 itr1 inc from other sources. have to repor last year it refund or only interest on refund?

While filing FY 2018-19 ITR1 - Under Income from other sources-

1)Under column 3 first mentioning combined all banks SB  interest ,  

2)then in next line all banks combined  FD interest (all banks have reported TDS in Form 26AS .but 2 banks have not filed TDS as my FD  interest earned just below Rs 10000. so have only interest certificate . so iam adding that FD interest amount also  in the total FD interest (so this total will be more than TDS 2 shown in the pre filled column ) 

3) adding another line : have to report last year total IT refund or only the interest on refund ? ( which is a small amount ) . form clearly say Interest  on last year It refund . just clearing doubt.Thanks
