A 30 years old client made a Roth IRA contribution 6000 in 0815/2020 for the year 2020, later she found the error and withdrawn the contribution plus earning 500 in 01/15/2021, no forms issued.

I believe I only need to report the 500 as taxable as ordinary income, right? Where should I report, 1099-R input? and what code should I use? Thanks a lot!
