Retirement tax questions

For 2019 my income is too high to take the deduction and I already paid taxes on the money I contributed

 

For the 2018 money I want to avoid deductible traditional IRA money mixed with non-deductible traditional IRA money so I would like to take the money out of the IRA or even just send that portion to a roth. Since I didnt claim the deduction I already paid taxes on the money. My questions is whats the best approach to do this while minimizing fees
