On my 2018 efiling to the IRS I got an IND-031-04 error

On my 2018 efiling to the IRS I got an IND-031-04 error -- either the PIN or previous years AGI didn't match. I didn't file my previous years' 2017 but I did complete my 2017 returns which I will mail in shortly. I used the AGI from the yet to be sent 2017 forms. What AGI should have I used for the 2018 efiling? $0?
