Income tax

ITR-7 u/s 139(4A) for AY 2017-18 by a Trust has to be digitally signed by the Managing Trustee.   But by oversight, the ITR was uploaded without digital signature and only available option is to generate and print Form ITRV for sending to CPC.  As the subject ITR has mandatorily to be digitally signed, the ITR and ITRV can be invalid.  Can the Trust immediately uplaod a revised ITR with digital signature by quoting particulars of the defective Origial Return?
