Form 8606 line 2-Nondeductible contributions basis

I am using Turbotax for the first time.

I have made nondeductible contributions in prior years, and did so again in 2024.

I have not taken any distributions.

When I print form 8606, my current year contribution appears correctly on line 1, but line 2 (prior years' contributions (basis)) is zero.

How / where do I enter prior years' contributions to correct lines 2 and 3 on this form?

THANK YOU!!!
