Itr2 tds scedule 2

While filling ITR 2 TDS Sch 2 when there is no TDS the total interest received on Fixed deposits cannot be shown since the green area is greyed. If we fill in as zero even then column 11 is greyed

Does that mean the columns should be filled only when TDS is deducted. For eg if Rs 100 is the TDS then in column 11 should we fill Rs 1000 or the entire interest amount. Should not these figures tally with OS schedule. IN ITR 1 it is populated by itself.
