I had the same issue. I tried using the auto fill 5 digit number that was in the pin box and it was rejected. I tried leaving it blank and the it prompted me to enter a 5 digit number of my choice and it was still rejected. I have the AGI from the 2019 tax return and it is correct. I did not file electronically last year but did file on time and did not have any changes to the tax return. This is very frustrating. I don't understand why there is even a box for the pin if it is not necessary and seems to be causing so many problems. Please help!!! Thank you
