I got corrected 1099 from Robinhood after my tax return was accepted
I got corrected 1099 from Robinhood after my tax return was accepted. There are few small changes on transaction records, that changed my net loss by $80 less. It won't affect my tax liability of 2020, but it will reduce the amount of short-term capital loss carryforward to 2021.
Do I need to amend my return of 2020? or just fill a reduced loss carryforward in 2021 report?
