Thank you for your reply.
Unfortunately, after spending 90 minutes on the phone with first-level customer support who just went around in circles, seeming never to understand the issue (actually marking my issue as resolved while I was on hold with them, offering me links to an unrelated issue), I finally convinced them to let me speak to a supervisor who agreed it was much easier to refund me for the purchase of the Indiana state return and I'll just fill out Indiana's PDF myself.
So, as a result, my Indiana return is no longer available in my return. To reproduce the problem, try to file a return that contains the IT-40RNR (non-resident Indiana income but resident of a reciprocal state). In my case, the numbers entered in 1A, 1B, 2A, and 2B were all entered by me. TurboTax failed to fill in any of the other fields on the form.
