@DanaB27 thanks for your reply. If I understand you correctly, I think you're saying that if I sell off the excess contributions plus earnings, then the 1099-R reflecting this activity will be reported in the 1099-R I receive in 2022, for 2021 return. But if I don't want to deal with tax filing amendments, then I can just file a 1099-R with my 2020 return showing this activity, even though I didn't technically receive a 1099-R this year for 2020 return. Is my understanding correct here ? If yes, isn't this sort of misleading because I'm saying I got a 1099-R even though I didn't ? Also, from IRS's point of view, won't this cause confusion even I'm reporting a 1099-R even though they didn't receive a 1099-R from my brokerage for my ROTH IRA account ?
