TurboTax can't cope with your two IRAs with basis that took distributions.

You would have to generate the  second Form 8606 manually and file on paper.

BUT, if you took no money from your own IRA, there is no issue.

If you elect to treat her IRA as your own IRA you won't have this problem next year.

@fanfare Are you saying that TurboTax can’t handle two 8606’s? I used it in 2019 after my wife and I both took distributions, and it filed two 8606’s.

I am telling you that TurboTax cannot produce two Form 8606 in your name.
