I filed with someone else last year. How do I e-file if I don't have a pin with you from last year?

A PIN is no longer required. Your last years AGI (Adjusted Gross Income) from your Federal return is all you need. If you do not have it you can contact www.irs.gov click 1)Help & Resources  and 2)under Tax Records click the second option down Order a Transcript of your Tax Return.
