About d saving amount which doesnot showed in the tax calculatin sheet when subimtted to ddo.

Respected sir iam an govt. Employee belongs to the state govt. I hav submitted my incometax calulation sheet in the month of febreary 2018 to my ddo . At that time i hav not showed my saving amount 10000 rs which comes under 80c in those taxcalculation.So i  hav paid more tax. Sir in the e filing i want to show my saving amount 10000 rs  under 80 c .So my tax will be reduced and it wil be refunded by incmtax dept. Suppose my ddo had completed the TdS process( 24Q).  My doubt is it is right to show my saving with out taking permission frm my ddo? If it is right process then i need to snd proper document related to the 10000 rs to the incmtax deprtment in the process of e filing ??? Plz clarify my doubt sir.
