ProSeries has a 'glitch' in this scenario.

The proper calculation goes back-and-forth until it gets an answer (or it gives up).   When the calculation goes past 400% of the Federal Poverty Level, ProSeries stops the calculation and denies the credit, even though calculation should keep going back and forth until there is an answer..

As was mentioned, manually calculating it (which can be gruesome) would give a true answer, but contributing to a deductible IRA or HSA would probably solve the problem as well.
