I don't understand why you need PIN?
If you use the "non-filers" tool it efiles your 2019 taxes.
It lets you create a new 5-digit PIN.
The non-filers is the only way I know for you to tell the IRS you exist.
Do you get any type of social security?
If you do, then they know about you.
If you don't, do the non-filers.
Skip the part that asks for an old PIN and give yourself a new PIN where it says you are allowed to.
