TDS - 26QB

Respected Sir, My request to you is as follows. My client purchased the property in August 2024 and paid 1% TDS on the property as per 26QB as the amount is more than 50 lacs. Now the client has received notice that 20% TDS has to be paid as Aadhaar is not linked with seller PAN number.

Now Seller PAN is linked

My humble request you what should I do next
