I opened a traditional IRA account with $6500 so I can convert it to Roth IRA for backdoor Roth conversion. I converted to Roth IRA a week later in 2023, transferring the entire $6500. However, because the funds were in my traditional IRA account for about a week, it started earning interest even after the funds have been entirely moved to Roth IRA. Currently, the balance on my traditional IRA account is $18. I don't plan on using traditional IRA for my retirement income. Is it better to close the account so I stop accruing interest income and hence pay taxes? What's my best course of action to save on paying taxes year after year?
