How to configure the UART-Usb port in a DE1 SOC fpga??

I have a trouble when I try to assign the pins of Rx and Tx UART ( my fpga is 5csema5f316N (Cyclone V SoC) in the Quartus II ( version 18.0) because the Table pins (I/O) show a reference PIN_B25 and PIN_C25 but these no appear in the pins planner of Quartus ( The device has the reference correct in the Quartus )

I need to receive bits in the fpga (from PC) and next to send them to pc ( I have a code project ready)
