Entry for receiving tds on provision

I am into providing services. The company that I provide service to has deducted TDS on provision on my account in March for the bill that I have submitted in April. Suppose the receiving company has deducted TDS on provision 2.5 Lakhs in March 2018 but I have raised a bill of 3.00 Lakhs in April 2019. How do I claim TDS on 2.50 Lakh and in which financial year?
