More information is needed for folks to comment. First of all, are you using a Windows PC or Mac computer?
What type of file are you trying to download from your Online TurboTax account--a 2024 PDF or the data file *.tax2024?
Are you downloading the file first to your computer before opening? What program are you using to open the downloaded file? For example, a PDF file would be opened in Adobe Reader or another PDF reader, or can be opened with a browser. In contrast, the data file can only be opened with 2024 desktop software.
