Check Deductions and Credits calculations in TurboTax

[Taxmemore]

After the check deductions and credits, I'm getting a negative amount in the State and Local Taxes greater than $10,000.  This is zeroing out the balances in the Mortgage Interest, Real Estate Taxes, etc.   

Any idea what is happening, as the program is defaulting to using the Standard Deduction?

Thanks

There is a $10,000 cap in the taxes paid portion of the Schedule A but I don't know why it is showing negative and zeroing out the balances in the Mortgage Interest, Real Estate Taxes. At this point you may wish to contact a specialist that can work through that section of the return with you. The specialists can look at your return on their screen to find out exactly what is causing this issue and suggest how you can take corrective action if needed.
