I sold some stick last year for the first time and had short term capital gains of 10.81 which was reported to IRS by E*TRADE. When I filed without the 1099, I only put down put down $10.00. I already received my refund for my 2020 taxes. Do I need to amend my return to add the 0.81 cents difference? Will IRS send me a letter of correction or to tell me to correct my return?
