The TurboTax update (macOS) on Jan 10 fixed the issue.
My normal process is to use the "early" release of TurboTax to do a final tax estimate before the end of the year, but the 2024 early release was NOT functional.
The property tax failure was not the only deficiency. It would not allow me to enter a pension distribution amount. It said that I need to wait until Jan 11 and download the amount directly from my fund!
I canceled my subscription to the early release. There is no benefit.
