Federal Schedule A state tax data not reported correctly for unknown reason

[tsbvirus]

The Tax Payments worksheet reads perfectly with all data entered.

The Tax and Interest Deduction Worksheet reports an incorrect amount for State taxes entered on lines 1h and 1i, which in turn then lists the wrong amount of state taxes on Schedule A line 5a.

This incorrect State Tax amount is carried forward beyond Fed Schedule A and affects also Federal Form 8960 as well as the State (CA in this instance) tax reporting forms.

I spent over one hour on phone with TurboTax help but never resolved the reason for this anomaly.  It appears to be a bug in the program that I would suspect might affect many other TT users.

There can be things included in line 1h of the Tax and Interest Deduction Worksheet that come from somewhere other than the Tax Payments Worksheet. On the Tax and Interest Deduction Worksheet, right click the amount on line 1h and select Data Source from the pop-up menu. It will give you a list of everything that's included, with links to where the amounts come from.
