If you used Turbotax Online version you will log in at https://myturbotax.intuit.com/. Start your return for the current year you will be asked if you want to upgrade to plus. If you are not asked if you want to upgrade, start the return by selecting take me to my return. Next select upgrade, if the plus button is greyed out you already have it, if not select it. You will want to fill out my info section of the return. Next click on Tax tools on the left-hand side, then print center. It will give you two options, one is to print previous years you do not want this, not yet. Select the first option at the top, print, save or preview this year's return. When you select this year it will then open up a screen to pay for the product, it reads pay now or later, pay now. Once you have paid you are not done, do not skip this step. Register the product then select continue. After this, you are ready to go to previous years return, select tax home, than previous years taxes. I hope this helps.
