The stored password list is a good idea! You might want to highlight that in your answer.

This is not enough information for anyone to help you.  For instance, what kind of wallet do you use (web wallet, mobile wallet, desktop wallet)?  Nobody can tell you how to recover your bitcoin if we know nothing but the address you received it to.

I've removed the address as it won't help in the discovery.
