I was able to have a tax accountant submit my 2018 return electronically in April, 2020.
If your 2018 return was filed that late, then try efiling the 2019 return using an AGI of 0 (zero) and leaving the PIN field blank. Or you can try it with an AGI of 0 and the 2018 PIN. An AGI of 0 is used when verifying a 2019 return for any 2018 return filed after November 2019, rather than the actual 2018 AGI.
In any case, it will still also ask you to choose a PIN to sign the return (any 5 digits of your choice), which can be the same one as used for 2018 or a new one. That's the PIN that can be used again next year, if desired.
