.tax is corrupt and but I have pdf

[rcarver62]

Can TurboTax convert my pdf to .tax file so that I can amend?

Sorry no.   Did you use the Online version?  Try downloading the .tax file again.  What year?  After 2008 it should have the year on it like .tax2020.  

Save the tax file

If you don't have the original Turbo Tax  .tax file you have to first recreate the actual wrong original return.  Start a new return, go to File-New.  You can use the Forms Mode.  Then when it matches each line that you really filed you have to tell Turbo Tax you will mail it so it thinks it was filed.  Then you can amend it.  You will have to print and mail amended returns.
