Even if you are sure you entered the correct PIN, go through the solution below to make sure you didn't overlook anything. We want to help you successfully e-file your return.
For tax returns that are rejected due to invalid PIN follow these directions found in TurboTax FAQ:
This is frustrating – you keep getting rejected for the wrong AGI even though you've copied it from the 2016 return sitting right in front of you.
For some reason, the IRS has a different AGI in their database. Your job is to find out what that number is so you can e-file.
Start by getting a free IRS transcript for your 2016 return. (Also get a transcript for your spouse, if you're filing jointly in 2017 and your spouse filed a separate 2016 return).
On your transcript, look for ADJUSTED GROSS INCOME (you may need to look on page 2). This is the number in the IRS database; make sure the AGI you enter matches this number exactly.
If you're unable to order an IRS transcript, try entering 0 as your AGI, assuming you haven't already gone that route. You can also try entering last year's signature ID (instructions below).
Failing that, you can opt to file a paper return; follow the solution steps above, except select File by mail when it appears.
