TDS Deduction on Technical services

Dear Sir,

We received technical service from Some "X' Company we did the payment on 30/06/2019 Rs. 2,29,000and 10/12/2019 Rs. 1,50,0000/- to them without deducting of TDS amount. We have not to pay the TDS amount till now. They rised another bill on 31/01/2020 of Rs.1,17,000, but we have not do the payment for this. What is the problem if not pay the TDS. If it is required to pay the TDS. Could we deduct the 3 bills TDS amount from January bill, what will be the interest calculation? please help reg. this.
