I am entering a backdoor Roth. I have done this on TurboTax for a decade. I am not being asked if I want to make part or all of IRA deduction nondeductible. Any tips?

I'm having the same problem, thought I was going crazy.

If your income is too high to allow a deductible IRA contribution, then you will not see a question about making part or all of your Traditional IRA contribution non-deductible.  

Instead, the assumption is that all of your contribution is non-deductible since you are not eligible to make a deductible contribution.  Therefore, the full amount of your Traditional IRA contribution is automatically treated as a non-deductible contribution without you specifically indicating this.
