After you file

Here's how to upgrade your already-filed 2016 return and pay for PLUS by credit/debit card.  If you have already tried and are already in PLUS, then do not upgrade any further.

NOTE:  Make sure you are in the same account as the locked 2015 return, or it won't work.

Since you have already filed the 2016 return, here's how to open it back up and pay for the PLUS.

  • Log in to TurboTax, and go to the 2016 Tax Timeline.
  • Scroll down to "Some things you can do."
  • Choose "Add a state." (you don't really add one; that's just to open the return.)
  • Once the return is open you should see an  Upgrade link at the top.
  • The minimum upgrade to unlock the returns is PLUS (29.99).
  • If you are already in PLUS, then the upgrade option for PLUS will be grayed out.  So do not upgrade any further.
  • If you are now in PLUS,  then you need to pay.
  • While the return is still open, click on MY ACCOUNT at the top, then choose PRINT CENTER.
  • Then choose "Print/save/view this year's return."  (yes, you say "this year's".)  You won't actually have to print it.
  • It should then prompt you to pay by credit/debit card.

NOTE:  If it should offer you the option to pay the fee out of your Federal refund, that cannot be done for this unlocking purpose.  You will need to pay by credit/debit card.

NOTE:   While you can use this method to open a return for upgrading purposes to unlock prior returns, do NOT use this method to open a return to make changes/edits to an already-filed return.   If you later need to make changes, you have to go through the formal amending process, and your return must start off exactly as originally filed.
