How can an NRI regulate banking operations in India

I am an nri for 20 years and all these years I have held several savings bank accounts , recurring deposits and fixed term accounts in Indian banks .most of these sb accounts are not actively operational now except those which are receiving fixed deposit interest by default and paying to rds All these fixed deposits were started by parents back in india before 2003. whenever I sent money to their resident account they used accumulate it and to make it residents fixed deposit ( for 24/36 months etc) and used to start recurring ac matching to its interest- mostly in co op banks All these fixed terms deposits are being renewed till now, though I continue as an nri. I do have a nre and nro account -to the only ones I am sending money since beginning of 2017. All my co op acs, fds & rds are jointly with my wife who is also a Tot value of all these now is abt 20 lakhs How can I regularise these co op accounts and fds now by simple means?
