After successfully completing the first iteration of my 2024 taxes without errors on Feb 23rd, I came back today, March 16th, to do round 2. There was a software update waiting for me, so I installed it (Application: 2024.r22.030 Build Date: Mar 16, 2025 at 1:08:57 PM).
The software now reports an error, which truly is a software bug. I have 2 copies of Form 1116 (both are legit). On the first copy, the error says Line 33 should be blank. The thing is, it *is* blank! However, line 35 seems to be the one actually in error, as that line isn't blank and it's highlighted in yellow with the amount in red. I have no explanation why that line would be in error, so I'm stumped about that, but that's probably a separate question and possibly related to the real bug.
(Interestingly, copy 2 also has a blank in line 33, but there is no error with that one.)
Anyway, by posting this, I'm hoping that TurboTax support will flag it, since there doesn't seem to be any other way to report a software bug.
