Can you use finite population corrector in getting the sample size of an analytic study?

Our research is about burnout and its associated factors. In computing for the sample size, we used open epi calculator, the one for cross-sectional study design. (We computed for each factor we wanted to associate and looked for the highest sample size.) We obtained a very big sample size (1000+), and it's more than our target population (610). Do we have to use the finite population corrector or is there a way we can reduce the sample size? (Is finite population corrector applicable for analytic studied?) Do we have to remove the factor for our study and just state it as a limitation?

Thank you.
