Retirement tax questions

Hi, I am in a similar situation. I put $6000 to a Roth IRA in 2020, and sold the stocks in Roth IRA in 2021 before recharacterizing to traditional IRA and gained $200 interest without paying any capital gain tax. Then I converted all the money including the interest to traditional IRA then to Roth IRA. 

Do I need to pay capital gain tax for the $200 interest? How to operate in Turbo Tax?
