Im in a right pickle. I cant locate my actual FIM address, but have my 12 word password that was created when i sent the FIM to......? Confused as hell.

EDIT: OK so i located the FIM account number through the NXT account they were originally sent to in 2014. Ive progressed the HEAT claim portal to a point where im asked to send the 1.9FIMK from the FIM account to.... FIM-4GY6-LCEB-BPEU-DZGGZ
How do i do that? From the portal im currently on? But thats not my FIM account, so.....?
