how do I find my PIN number from last year on line
You didn't say what kind of PIN, so I'll make an assumption below.
. Are you referring to a 5-digit PIN entered in the FILE section when efiling? Or are you referring to a 6-digit IP PIN (Identity Protection PIN) assigned by the IRS to victims of ID theft (or to those who opted in to that program?) An IP PIN is entered in a different section.
Since people are most commonly asking about the 5-digit PIN, that's what I will address. Last year's 5-digit PIN (aka "Prior-Year PIN or Self-Select PIN") is not necessary to verify a 2021 return for efiling. To verify your return for efiling you can use the 2020 AGI (most common) instead of using the PIN field (less common.)
There is a later screen that asks you to "Sign" the return that wants you to enter a 5-digit PIN (it tells you to choose any 5 numbers you want). It's on a screen with today's date and your birth date. The numbers you choose to enter on that "signature" screen is called a Self-Select PIN and can be used again next year, if you save it in a safe place.
Even though last year's 5-digit PIN Is not needed, some people may be able to find it. It may be easier for desktop users than Online TurboTax users. Among the worksheets is one called "Federal Information Worksheet." Near the bottom of Page 4 of that Worksheet, the 5-digit PIN might be displayed. Online users would need a full PDF containing the worksheets, and some Online users reported that method didn't work for them--that it wasn't on their worksheet. But again, the 5-digit PIN from last year is not needed if one uses the 2020 AGI for efile verification.
