Generally speaking, I would wait at least one month after discharge for everything to update and report correctly. If you find errors after that, then I would start addressing them. During the bankruptcy procedings, your credit reports will be in flux and potentially all over the place.
Some people will say right away and to start disputing anything not $0 bal/IIB right away. While proactive, I think this can be spinning your wheels because things are still in the process of updating. I waited about a month and had I think everything except 1 account was reporting correctly.
As others have said give them a month or two to update reporting. After that pull your credit and see what it says. If you can't wait there are plenty of places that offer free credit reports (Credit Karma, VantagScore) that will show you your report and how it is listed.
