Is access to the 2015 return locked because it was prepared in Free Edition? If you can't get the free 2015 return transcript by downloading it at the IRS link above, or don't want to wait 5-10 days for it to come by postal mail, we can tell you the steps to upgrade to PLUS and pay the 29.99 by credit/debit card to unlock the 2015 return.
NOTE: If you already did upgrade to PLUS, then whatever you do, do NOT upgrade any further, or you'll have problems. We can tell you how to pay for it.
How to upgrade and pay depends on what you have done for your current 2016 return. Have you already filed your 2016 return with Online TurboTax, or is it still in preparation? Was the 2016 return in Free Edition? Or was it prepared outside of TurboTax?
And is the locked 2015 return in the SAME account as the one you used/are using for the 2016 return?
