I downloaded Turbo Tax but can't find my activation code. It disappeared when the program restarted my computer

I ordered mine from an obscure turbotax that only sells downloads.

They sent 4 emails.

1st was confirming my order.

2nd was giving notice that a note was added to my order.

3rd was an email of that note.  It has the registration code or activation code needed for your turbo tax.  Also link included for downloading the .exe file that installs TurboTax.   <-- that 3rd is the most important one.  Is also the smallest number characters.  The Activation code is 16 chars, 4 groups of 4 chars.  (Capital letters and numbers)

4th was email confirming order completed.

Please see the Help Article here on how to obtain your license code.
