What year was my bankruptcy discharged

Why don't you go to the court and look it up yourself or call them?

Easier than that:

Google PACER.

No one here can tell you, you will need SS# ( do not post here) or case number.

You would have gotten a discharge letter from the court, and also it should show on your credit report.

Next it is not looked up by the building name but by the Federal Bankruptcy court

Yep. The particular courthouse named by the OP appears to be in Atlanta.
