Deductions & credits

While trying to enter my Virginia Car Tax I get two different reply's from TurboTax Premier.  1, "Hmm, looks like we've hit a snag  -- We recommend you revisit the last topic you were working on to make sure all your info's correct."  2. The other reply is - "We've got all your property tax info -- Looks like you've maxed out the federal $10,000 amount for itemized deductions."  

There is a bug in my copy of TurboTax Premier desk top.  I have down loaded all the updates.  I have been using TurboTax for over 10 years and never had a this problem.
