2020 PIN
Are you referring to the 5-digit PIN you used to sign your 2020 return last year?
If so, last year's 5-digit PIN (aka "Prior-Year PIN or Prior-Year 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) in the AGI field instead of using the PIN field (less common.)
Be aware that later on there is another 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.
