Thank you for your reply. We were able to chase down what happened. The building itself has a depreciation amount attached to its appraised value at the date of inheritance. For some reason that amount, in addition to being applied as normal depreciation, also ended up in the capital loss carryover fields. So the amount was getting deducted twice!
We were unable to enter 0 into the 3 fields where the capital loss carryover number was; Turbotax refused to accept 0, and when we tried the other option (No) it refused to save that, or change the numbers! We found instead that entering .01 (or, I assume, any amount <= .49) would make it round down to 0.
Once zeroed our federal vs state income returned to the match it should have been.
A piece of advice to everyone with moderately complicated taxes: when you download, make sure you include all the worksheets in your download. This is not the default.
