All my files are on an external drive and cannot be on drive C. Turbotax does not recognize at all the mapped drives on my PC. How do I access mapped drives?

When you need to load previous year cannot load previous year. They are on external drive mapped through a drive letter. This is not uncommon.

TurboTax does recommend that you keep the tax files on your main computer to open it and the steps are detailed in this link.

However, while this thread is a bit older, there are some suggestions that might help you troubleshoot and open the files on your external drive.
