@SteamTrain 🙂 Same problem on my wife's macbook. Asked someone to try this on Windows. Neither problem occurs. Window's TurboTax viewport window appears about the same size but it looks like it uses a smaller font so all columns show up.
yes, opened up a second file while having my 2023 return file open. Modifying the second file looks like it modified the data in the first file. Looks like a bug. Probably have to file a different bug report elsewhere.
This problem doesn't occur on Windows because the TurboTax Windows version forces you to close one file before starting on another.
