Hello, @LINKSAT. 

Depending on the incorrect information you've entered, you can view the audit log. You can use the data from there as a reference in entering the correct information.

Here's how:

1. Go to the Gear icon.
2. Under Tools, select Audit Log.
3. Review the details of the user who recently logged in and the information entered on it.

You can use this article to learn more about the audit log report: Learn About the Audit Log.
