After you file

Me personally I always keep the last 3 years on file in my home. If anyone's going to ask you it's going to be for the last three years as I've worked in Human Resources before. But don't stress if you can't get it off of TurboTax you can always go straight through the IRS and Prince everything off their website or go to an IRS office and they will print it for you. My suggestion is to get the last 3 years always always always keep that on file.
