In my last year's tax form (1099 form) from a brokerage company (TD Ameritrade), I don't find my loss realized when I sold some mutual funds last year. TD Ameritrade said that the 1099 doesn't calculate gains and losses, but they offers the Gains/Loss Tracker on the Web site to create a Schedule D.
My concern is that my loss is not shown on my 1099 form, and how IRS can know my loss? Is it possible for me to claim the loss on my tax report? How I can claim the loss?
Also my income was less than $20k last year, so I will expect all my withheld Federal and State tax back. Given that, shall I still report the loss of my mutual funds in the tax report for last year? Can I not do it now, so that I can save it for the future when I have more income to use it to offset my income tax then?
(Sorry this is the first time I have to deal with such a case)
