Is there an R function to adjust scale in the axis for a barchart?

I have a dataframe called crashes_deaths_injuries_TA_pop that looks like:

TA_name Population
Gore 34466
Buller 444444
Cluth 34455

I am trying to show the data with a bar chart however, the scale of x-axis is messed up and I'm not sure how to . I know this must be easy but I am new to coding so I am struggling.

here is my code for the bar chart:

ggplot(crashes_deaths_injuries_TA_pop, aes(x = reorder(TA_name, Population), y = Population, fill = Population)) +
  geom_col(alpha = 0.7) +
  scale_fill_distiller(palette = "Reds", direction = 1) +
  coord_flip() +
  labs(x = "", y = "Population", fill = "Population",
       title = "Populations of South Island TA's | 2018",
       caption = "Data: Census 2018, StatsNZ") +
  theme_minimal() +
  theme(legend.position = "none")

I was also wondering how can you add like the population as a number at the end of each bar for each TA_name

Use scale_y_continuous(breaks = ) to edit ticks of x axis of yours and use geom_text to add Population next to the bar chart. Here's an example.

ggplot(crashes_deaths_injuries_TA_pop, aes(x = reorder(TA_name, Population), y = Population, fill = Population)) +
  geom_col(alpha = 0.7) +
  scale_fill_distiller(palette = "Reds", direction = 1) +
  coord_flip() +
  labs(x = "", y = "Population", fill = "Population",
       title = "Populations of South Island TA's | 2018",
       caption = "Data: Census 2018, StatsNZ") +
  theme_minimal() +
  theme(legend.position = "none") +
  scale_y_continuous(breaks = seq(0, 5e05, 0.5e05)) + geom_text(aes(label = Population, y = Population+0.18e05))
