I'm interested in plotting KM plot for assessing the OS. But while plotting I'm not getting any value significant (p-value < 0.05). Is my code correct?

JMS <- read.delim(file = "LUAD_SURVIVAL.txt")
JMS = JMS %>% mutate(group = case_when(TDRKH> quantile(TDRKH, 0.5) ~ 'TDRKH(High)', TDRKH < quantile(TDRKH, 0.5) ~ 'TDRKH(Low)', TRUE ~ NA_character_ ))
fit <- survfit(Surv(Time, Status) ~ group, data = JMS)

ggsurvplot(fit, pval = TRUE, conf.int = TRUE, conf.int.style = "step", risk.table = TRUE, risk.table.col = "strata",  break.time.by = 1000, linetype = "strata",  surv.median.line = "hv", ggtheme = theme_bw(),palette = c("#E7B800", "#2E9FDF"))

My Data in LUAD_SURVIVAL.txt is:
