Tds deduction on contract

TDS has to be deducted on booking or payment, whichever is earlier.
So, you have correctly dedcuetd the TDS.
There will not be any problems in showing it in the return as you can show it as a deduction for the month of January. The fact that the actual payment was made in Feb is irrelevant.

Also, I hope you have considered the ST as per reverse charge.
The liability to pay ST on works contract is on the service receiver.
