Form 8606T Line 15c Taxable Portion of IRA Distribution Not Calculating

[Manny]

Pro Series does not calculate the taxable portion of an IRA distribution on Line 15c on Form 8606, Non-Deductible IRA, which is supposed to separate the IRA distribution into the nontaxable return of basis and taxable income portion, which is Line 15c.  I have the 1099R Normal Distribution Code indicated and the IRA box checked, and yet none of the IRA distribution flows to the Line 4b on Form 1040.  If I uncheck the IRA box on the 1099R input screen, then the full distribution is reported as taxable on line 4b Form 1040.  This problem occurs on every 2020 tax return with IRA distribution in which the taxpayer has basis from prior year’s non-deductible IRA contributions.  Is this a ProSeries software defect?  Any solutions?
