Business & farm

I have trading losses that were incurred prior to FTX.US bankruptcy that I want to report as a capital loss. I do not have a 1099-B from FTX.US to show my transactions but I can calculate the total amount of trading losses by subtracting my account balance on the Debtors Schedule and Statements from the amount of deposits I made to my FTX.US account. Can I report a capital loss if I do not have any transaction details?
