If both spouses took IRA distributions, both have non-deductible basis and the IRA info wks data is correct for both spouses, why is the 8606-T created but not 8606-S?

IRA Info Worksheet has values in lines 1, 2, and 3 for both Taxpayer and Spouse.  Both has basis carryover from 2019.  Both taxpayers took distributions from their IRAs. The values in the IRA Info Worksheet are accurate.  But only the 8606-T is generated.  I cannot get the 8606-S to generate.
