For the past 3 years I been having a loss on my stocks. I did not claim because I did not know I could get a credit to use for next year. I already filled my 2019 taxes and received my tax refund already.
1) Is there anyway I can go back to claim my loss for 2019 or before so I can use that as credit for 2020?
2) What form is used for stocks?
2) Any tips?
Thanks,
RP
