Form 26qb correction as a nri taxpayer

Hi,

Recently i purchased a property and deducted TDS on agreement value. While filling tds using form 26qb, PAN number of buyer and seller is interchange. As a NRI tax payer, option for online correction request is not available on traces website.

Can somebody guide me on how to correct the form 26qb and what procedure i need to follow. 

Thanks in advance.
