Resolved after a long time on a Tech Support phone call. Thank you Gladys from Tech Support! You were very patient and helpful.
Had to go to the upper right corner and click Forms. Then clicked Schedule A. Scrolled to Taxes You Paid (5c). Clicked in the 5c box, which then jumped to the Tax and Interest Deduction Worksheet; scrolled down to State and Local personal property taxes, line 3c, where I could finally click in the box and enter my supporting details and amounts.
This is a terribly cumbersome way to do this. It was always much, much easier in the past, when you could just enter numbers and supporting details as TT walked you through the entire process very simply and directly. I am seriously thinking I may abandon TurboTax next year after 26 satisfied years.
