You did a Roth conversion and must report it as such. A Roth conversion is irrevocable. There would be no benefit from treating it as a recharacterization anyway unless you have other funds in a traditional IRAs.
You can have the option to make the IRA contribution nondeductible even if you qualify for deducting the IRA contributions. As long as you have no other funds in a traditional IRA, there is no tax difference between making a nondeductible traditional IRA contribution and converting to Roth, and making the contribution directly to the Roth IRA.
Even if you deducted the traditional IRA contribution, the only difference would be that it would be 5 years before you could withdraw the converted funds without penalty if under age 59½. Your AGI would still be the same with the IRA deduction offsetting the taxable income from the Roth conversion.
