At what point in the secured party/creditor process can one start filing the relevant 1099’s to “claim back” the abandoned securities

I have heard of this, claiming back all the checks you wrote , the debit card withdrawls, the wire transfers- we can claim those transactions, correct? do we need to have a trust bank account opened in order to do so? how does the claim come back to you, as a check from the treasury or is it just deposited to your "money of account" (credit) w/ the treasury dept?

thank you
