INPUT CREDIT FOR THE FY 2019-2020

By mistake One purchase bill not shown for the month of Feb 2020, so no input tax taken on that purchase bill for the month of Feb 2020, but now For the Month of May 20 that purchase is taken into consideration for claiming input tax credit. 1) Should i avail input tax credit for the month of May 20 ?

2) What is the maximum time limit for utilization of Input Tax Credit for the FY 2019-2020 ?

Regards.
