For a resale, you are usually "in the system" within 10 business days after your actual closing. You may need to get the Member Services phone number from your realtor or closing agent and start calling MS after about a week.
When we closed, we were "in the system" in name only at 9 days, meaning we were in the computer, but no points had been posted to the account. The points went in the next day.
Be sure to double-check the points to be sure they are correct. They do make rare mistakes, and it's a lot easier to get issues resolved quickly.
