Items normally stay on your credit report for at least 7 years. Whether a loan is paid in full on time and paid off, or paid late and goes to collections, its still listed on your file for at least 7 years. I couldn't say why a bail bond would be listed one month and gone the next. Maybe the credit bureau decided it wasn't really your debt and shouldn't be listed. Or some other glitch.
You can start by getting your full reports from all 3 credit bureaus at www. annualcreditreport.com. See if this is listed on some, all, or none of your reports. Then, if you wanted more specific information, you can call Transunion and ask, since that's where Turbo gets its information.
