wher as my tax return file?

If you are trying to locate your downloaded tax file, here's how you would find it:

Windows: Find your tax data file (.tax file) in Windows

Mac: Find your tax data file in Mac

If there's something else that you're needing assistance with, please specify.

If you are looking for your online tax return.....

It's common to end up with multiple accounts. First LOG OUT of whatever TurboTax account you're logged into right now. Then use this TurboTax account recovery website to get a list of user ID's for an email address. Run the tool against any email addresses you may have used

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online.
