Retirement tax questions

Thank you @dmertz for your help.

 

The traditional IRA has both after tax contribution $6,500 and the interest income $5.40 which is taxable. Can I convert them all to the Roth IRA in 2024? What is the tax implication if I do it? Previously all conversion are for after tax money entirely. Or I should convert $6,500 to Roth IRA and keep the $5.40 still in traditional IRA? Thanks.
