Turbotax not calculating new IRA basis after distribution

[jedelman10]

Years ago we made after tax contributions to our IRAs. When we started to have IRA distributions in 2021, I failed to include the IRA basis so the pro-rata rule was not used. I am now trying to amend my returns to correctly calculate the IRA basis and to get a refund on the taxes we paid 2022-2024 on after tax contribution distributions. I cannot get Turbotax 2021to use the pro-rata rule after entering the total basis as of December 31,2020.(I checked the 1099-Rs for the IRAs and the IRA box was checked for the IRA distributions.) It says my IRA deduction is $0. I went in manually to the worksheet and entered the total value of the IRAs as of 12/31/21, but that did not change the results. How can I get TurboTax to do the correct calculation?

I think I figured out what I was doing wrong. No need for anyone to bother with this.
