yup that's a conversion
but the conversion is part of your 2025 taxes not 2024, all you should put into your 2024 return is the non-deductible contribution to the Trad IRA, which will be reflected as a basis in your IRA online 14 of Form 8606 which carries forward to 2025.
Roth conversions are taxed by calendar year, when you get the 1099-R for 2025 you would then include the conversion in your 2025 taxes.

Check there was no misunderstanding with your brokerage also if you asked them to "recharacterize" it - check the transaction was classified as a contribution to your Trad IRA and conversion to your Roth IRA (which is just a transfer between IRAs), not a contribution to your Roth IRA. You should also have Form 5498s showing the contribution to the correct account.
