Am I getting any benefit by being in a Traditional IRA if I am funding it with after-tax dollars?

I current have a Traditional IRA that I fund with after-tax dollars. I put the maximum of $6k in each year. I am not able to take a tax deduction for the Traditional IRA because my income is over the limit that allows for deductions… so as far as I am understanding, the Traditional IRA is not benefitting me, right?
Instead, I should roll over into a Roth IRA, right? So that I am not taxed when I take money out in the future, and because there is no tax benefit to me today? Thank you for helping!
