How Do I handle the interest generated in the traditional IRA account after i do the back door conversion?

In December 2023 my daughter contributed $6500 for 2023 traditional IRA then 5 days later we did the back door conversion of $6500. She just saw there were $5 left in the traditional IRA account. She plan to contribute $7000 for 2024 and do back door again. But how should she handle that $5?

in the 1099 R -1a- $6500, 2a- $6500 , code 2 on line 7. In the turbo tax she answers:

What did you do with the money?   I move to another retirement 

                                                                I did a combination

                                                                Amount $6500 converted to Roth

Let find your IRA basis.                      As of December 31 2022  $0

Value of your traditional IRA as of December 31 2023 : $5

But when I looked at the form 8606 :

                                Line 14  :   non taxable  amount :  $  6495 

                                Line 18 : total basis : $5 ( include this amount in 2023 line 4b)

Line 14 is not the same as the amount in the form 1099 R . Is this ok ?

In short when can she move that $5 to the roth? Can she move it with the $7000 when she contributes to 2024 IRA? Should she clear the traditional IRA to $ 0 before she do another back door this year?

Thank you for helping
