What 1045 Form and Instructions do I use then? 2011, 2012, or 2013 version, carrying back to 2011 first ? Can I file the 1045 on or after I file my 2013 return? What if I can't locate my 2011 return? Will a Transcript from IRS be enough to get the information? Do I need to pay for a copy of my 2011 return. Can I choose to only carryback to 2012?
