I incurred capital loss in 2018 due to selling stocks in December 2018. But when I was preparing my taxes, I did mention only capital gains (since at this time December transactions were not ready yet). So, I've filed about $700.00 of gains instead of real about $5000 of losses. What should I do now in 2020? Do I need to do an Amended Tax Return via TurboTax? Or any other advice? Thanks!
