If your income is high enough, yeah. If you (and your spouse, if married) DON'T have access to workplace retirement, then a tIRA is always deductible. If you do, the deduction is subject to income limits.
How high is your income? If you're eligible for Roth IRA regular contributions, what you want to do is recharacterize the contributions to Roth. If you're above that limit as well as the tIRA deduction limit, then you probably want to do a backdoor Roth IRA - conversion. There are quite a few gotchas there, given you got to this point by accident. I think you can also request a return of contributions.
