How do i pay for plus to access my prior tax return?

[mesquitebean]

When you try to download the prior return, does it ask you to upgrade and pay?    If it was prepared in Free Edition last year, access will be locked.   If that's your situation, we can tell you how to pay to unlock your 2017 return.  Normally one will need to upgrade a 2018 return to PLUS and pay 19.99.   The method to unlock it depends on what all you have done with your 2018 return.

Please answer all of the following:

1. Have you already filed a 2018 return in Online TurboTax, or is one still in preparation?  Or did you file elsewhere?
2. Is the 2018 return in the SAME account as the 2017 online return?

We can tell you how to unlock a return once you answer all the questions above.

If all you need is the 2017 AGI, there should be a free link under "Your Tax Returns & Documents."  When you expand and choose tax year 2017, look for a link "View adjusted gross income (AGI.)"

There's also a free option if a return transcript will suit your purpose.   You may be able to immediately download one at the IRS website if you qualify to open an IRS account there.  Otherwise, to order a transcript to come by postal mail takes 5-10 calendar days.
