Depends, a repo stays on credit for 7 years, and a bankruptcy stays for 11 years, after you have paid off a debt and they have received payment it should be taken of immediately, but you may want to get a free credit report and check and if it is still there call them and ask them about it.
If you miss a payment or make a late payment within 30 days of the original payment due date, that goes on your credit report and stays there for seven years. Once you become 90 days late on paying a bill, your account is closed and sent to a debt collector, which also stays on your credit report for seven years.
