TDS Paid for Two Years

We have done Contract Work. Our Party has not deducted TDS and paid full payment to us in 2017-18. In 2018 - 19 our party is deducted the TDS on all payment made to us since 2017-18 to 2018-19.

Please Clarify the below queries :

1. Can we take the prior period income/expenses of 2017-18 in 2018 - 19 P/L A/c and to claim the TDS deducted amount.

2. Any effect in current year (2018-19) P&L A/c due to added the prior period income/ expenses of 2017-18.
