Clarity on 26qb in case of minor being the owner.

In our case, I had booked a flat in the name of my minor daughter aged-10. In the past 8 installments, I had filed form-26qb on behalf of my daughter using her PAN card. Now the system has changed, Form-26QB can be filled only after logging in Income Tax Site. Since my daughter is a minor, IT department is not allowing her to register herself in IT site. Now we are facing problem in filing 26QB. As per Income Tax Customer care cell, i had applied for Representative Assessee on behalf of her, but it got rejected three times on account of her nil income. She is a normal child stadying in Standard-V having no own income.

May please suggest how to file 26QB in her name??

Kindly help me for an amicable solution.
