DarenG,
My apologies for a late reply. I also volunteer with AARP TaxAide and was tied up for the last few days providing remote assistance for folks preparing their taxes. I assume you already pored over the various state tax credit options quite thoroughly.
If the version of TurboTax that you are using has a Forms view, then you can go to forms and worksheets to directly override many values. (I use a version that is installed on my PC.)
