GSTR 7 for the month of August 2020 wrongly filed by me for deductee Say "A"

 On our request deductee has rejected TDS details. 

Later refund request filed for refund of TDS along with Interest and late fees for return wrongly as per 

 Refund disbursed as per Order   on 14/01/2021. 

 But during filing of GSTR 7 for month of  March 21, TDS rejected by deductee auto populated in Amendment tab – Rejected by deductee column.  

When I am trying to change details in Uploaded by Deductor TAB in TDSA system saying “DEDUCTEE HAS ALREADY TAKEN ACTION AND FILED” .  

System asking me to first modify TDS details Rejected by Deductee then file New return for March 2021.

If I File Return again then it will again show in Deductee system requiring him to either accept or reject TDS detail.

I want Return for August 2020 to be deleted as it is Wrongly filed and hence irrelevant.

Hence Please help me in removing this Wrongly filed return for August 2020 for which refund has already claimed and disbursed
