Hello,
while RM0394 talks about CH18SEL and CH17SEL, in
16.7.2 ADC common control register (ADC_CCR)
stm32l412xx.h only knows ADC_CCR_TSEN and ADC_CCR_VBATEN .
While the names in stm32l412xx.h are know to me from other devices, the names in RM0394 are new to me. I suggest changing the names in Rm0394 to the names already used.
