1% TDS Deduction on Property purchase through installments in 26QB

I have purchased a property as per the following detail:-
property value is ₹56,30,000
Payment 1: ₹3,00,000 on 02-11-2025
Payment 2: ₹39,22,500 on 01-12-2025
Date of Agreement: 08/12/2025
Payment Remaining: ₹14,07,500

Now builder is asking to pay 1% TDS to be paid as per 26QB and give them Form 16B.
Now my questions are:-
1. Shall I have fill up two Form 26QB for two installments ?
2. Will separate Form 16B will be issued for seperate payments ?
3. Will there be late fine for ₹3,00,000 ?
