That $100 is from 2020 contribution, another traditional IRA.
I have two Roth IRAs and two traditional IRAs, under two brokers. All contribution is after-tax money.
I didn't know much about Backdoor Roth Conversion, that is why I am asking. Now I am thinking to convert all the money and bring both traditional IRAs to $0 balance. Doing so, I don't need to carry Form 8606 for many years.
In the future, if I make non deductible traditional IRA, I should convert it right away, at least convert it in same tax year. No need to carry Form 8606.
