It refund in case of 26qb filed by taxpayer

Hello,

By mistake we have paid Excess TDS of Rs. 1,10,000/- & for that we have already corrected 26QB Form & this excess amount is reflecting in our 26AS part 2 but at the timing of Income tax return filing we claimed this Amount as refund, but no refund given by income tax dept. then what is the procedure of claiming refund because we are not having the TAN Number, we are the taxpayer & there is no option available in taxpayer login on traces for Claiming Income tax refund
