the 2010 tax file cannot be opened or printed even if you have the app/cd because it is no longer supported. also, neither the IRS nor Turbotax would have copies of the 2010 return. returns/tax files are only maintained for 7 years. if you have the xxxx.tax2010 file there is a website unaffiliated with Turbotax/Intuit that may be able to print out a copy of the return for a fee
