Your attorney will provide you that opportunity if it's important to your case. What you need to do is to answer the question you're asked and only the question you're asked. Remember you're under oath. You're effectively swearing to everything you say. If you're not sure of something, or if you don't know something from your own personal knowledge, don't say it's true.
Court reporters are surprisingly accurate, but everybody makes mistakes from time to time.
Make sure the transcript is accurate. If you discover later that something you said in your deposition was wrong, tell your attorney. This will allow your attorney to understand the discrepancy quickly and completely.
