Umm, no. It's in stm32l4xx_it.c file.

But you shouldn't need to do anything in that file anyways. All your coding would be done in the callbacks which are in stm32l4xx_hal_uart.c or stm32l4xx_hal_uart_ex.c. You just override the weak callbacks that you want to use.

Are you looking at the correct file where it gets generated?

the IRQ handler should be at main.c ?
