Entering the prior year agi or the prior year self-select pin are merely a requirement to qualify you for e-filing your current year return.
You might try entering a 0 for your prior year agi to see if it will work and let you continue with your return. There are several conditions where IRS says you should use a 0 prior year agi.
At this point, being able to e-file your return is the goal. Try the $0 and see.
Here is some additional information from IRS:

When self-preparing your taxes and filing electronically, you must sign and validate your electronic tax return by entering your prior-year Adjusted Gross Income (AGI) or your prior-year Self-Select PIN.
Generally, tax software automatically enters the information for returning customers.
If you are using a software product for the first time, you may have to enter the information yourself.
