"Reporting of the charge-off" is done under more than one code, referencing different aspects.
For any month when the account was delinquent, it will have had a delinquency status that can be reported and retained in your Payment History Profile as an historical record of past monthly performance. It can show, for example, either "180+ late" or "CO," either of which store the history profile.
Separate is the Current Status, which reflects no historical information, and is only a snapshot of your status as either delinquent, paid, or pays as agreed as of the date of the last reporting. After the debt is paid, the account is no longer delinquent, and the current status must be a non-delinquency status. "CO" could then no longer be a proper currrent status.
In the posted scenario, the Payment History profile can continue to show CO for each month after it was charged-off until it was paid in 02/2016. After 2016, regular updates should have ceased, adn the CRAs instruct creditors to cease updates no later than 3 months after the debt is paid, but if any updates were made, they should show OK from 03/2016 to date, with the current status with each update reporting Paid.
With the Current Status no longer being one of delinquency, then when the account reached 7 years from DOFD and the CRA was doing its exclusion, their policy is not to exlcude the entire account. They exclude for all months in the prior Payment History Profile, and the Currrent Status would show Paid.\
Deletion of the entire account would only occur if its Current Status remained unpaid (e.g., "CO").
Thus, your account thereafter would show no derogatory items.
If they are continuing to show any delinquency status after you paid the debt, either in your Payment History Profle or as your Current Status, that is inaccurate, that is a violation of the exclusion requirment of FCRA 605(a), and you should file a dispute on that basis.
