Query Regarding TDS on purchase of property

My parents have bought an apartment in India worth 60 lakhs inr. Registration completed on June 2021.However, we were not aware of the requirement of deducting TDS and paid the amount in full to the builder.Now he is asking us to pay the TDS amount to govt website from out of pocket.

1. Can you please help what are our options here if the builder doesn't refund the TDS amount.

2. Also will we as buyer be solely responsible for not paying the TDS to government

3. Will TDS be calcukated on total 60 lakhs? Will there be any penalty and interest applicanle on us as buyer?

Thanks in advance for your help!!
