Stamp duty value in form 26qb

A person had booked a flat in 2011 and was given allotment letter.The booking value was Rs 1.36 cr and advance payment was 30%. I bought this flat from that person by transfer of allotment letter in 2016. The builder transferred the allotment letter in my name. The agreement was executed in January 2019 due to substantial delay in execution of the project. I had to pay stamp duty on sdrr rate of January 2019 which was Rs 1.92 cr. I had been deducting and paying TDS on all installments. Now I have to pay the final payment and take possession. In 26qb form the moment I say final payment it is asking me the stamp duty value. Builder is telling me to put sdrr rate of 2011 which is around Rs 62 lacs and actual stamp duty paid by me is on 1.92cr. If I put the value of 1.92cr the TDS automatically changes and increases by Rs 30000/- due to difference in agreement value and Stamp duty value. Please advise what figure has to be inserted in stamp duty value.
