One week following my initial phone conversation with TurboTax, I called again this morning because I didn't see any changes during the past week. Today's rep remotely connected into my return and agreed with my assessment. After an hour of hanging up the phone, the rep called me to explain a way to work around the issue.
You can override the calculation on a screen located in the State module under Income (not Credits - even though it is an adjustment that affects the Itemized Deduction Credit). Once I hard-coded the correct number in the field, my state return reflected how I thought it should have looked. I was able to e-file my returns today following this set of instructions.
I was using the online version for Windows - Deluxe package.
