How do I open my e-filled 2013 Turbo Tax return? It’s in my saved files. However, when I try to open it, it says open in OUTLOOK. I have OUTLOOK ~ doesn’t work

If the 2013 return was saved as a tax data file, it will have a file extension of .tax2013 and can only be opened by the TurboTax software for 2013.  TurboTax does not support tax year 2013.

You can send the file to this website and for a fee they can provide a PDF - https://www.taxprinter.com/

If the 2013 return was saved as a PDF, it will have a file extension of .pdf and can be opened by any PDF compatible viewer, such as Adobe Acrobat.

2013?   If you did not save the return as a pdf, you will not be able to open it unless you also still have the 2013 software program.   If you only have the tax file, you could try using a service called Tax Printer---they are not affiliated with TurboTax, and we do not know what the cost would be to use taxprinter.com
