I cannot get line 15c on Form 8606 to populate. Therefore the taxable portion of the IRA distribution does not carry forward to the front page of the tax return.

Went back to a prior filed return with 8606 working properly in 2020, but when I called the return up, line 15C on 8606 ceased to populate.

There has got to be a program error on an update.

I have used 8606 many times without a problem this year and in past years.

Can someone look into this?
