Do you have the tax return file ending in .tax?  It  either ends in .tax or .tax2007.   I don't remember which year they started adding the year to the file extension.  UPDATE, I found my notes...... Starting in 2008 the tax data files end in .tax2008, .tax2009, etc. Before 2008 they just ended in .tax. 

Where did you get the .tax file?  Did you use the Desktop program or the Online version?  You didn't save the pdf file?  

To open a .tax file you need that year's program installed.  It is too late to get the 2007 program or install it.   OR you could try the TaxPrinter service to convert a .tax file to pdf at

They might be expensive and it is probably not safe to email tax returns back and forth. They are not related to Turbo Tax. I see it says federal is $44.99 and Federal + state is $79.99.
