I believe I am calculating my sample size incorrectly. May someone provide some input? I am having a hard time understanding population and population proportion. 

The population I want to sample is Hmong Americans with disabilities between the ages of 18-64 across the U.S., which comprises about 16,090 individuals. The 2021 US Census states that this group is 7.6% of 211,705.

16,090/211,705 X 100 is approximately 7.6%.

211,705 refers to all Hmong Americans between the ages of 18-64. When I calculate sample size, I am assuming these standard values: confidence level is 95% and the confidence interval is 0.05. However, I am lost on what to put for population and population proportion. This is what I have gotten so far, and I am not sure if it is correct...
