Correct, but that is not what the current TurboTax calculation is doing. 8c is 8a-8b. And then 8c gets transferred to line 25. What the TurboTax software is doing, I believe, is transferring 8a instead of 8c into line 25. It shouldn't be doing that (unless you opt to defer the non-refundable portion of the tax break). I called the IRS and they confirmed this. I also ran the exact same calculation through H&R Block's software, and got the correct output (meaning H&R got the same number as my payroll and what the IRS told me it should be). So TurboTax needs to update their code (which they acknowledged and are in the process of doing).
