that s the correct code for a Conversion - it means that you are not subject to the 10% penalty, but it is a taxable event.
did you answer that your TRAD IRA basis on 12/31/23 and 12/31/24 was zero?
there is a question that asks what did you do with the money? answer should be "moved it to another retirement account", then the next drop down should be "did a combination of rollover, converting, or cashing out the money'.
the next drop down answers how much was converted to a Roth IRA. (answer for you $8000 to Roth))
is that what you did?
