2019 tax filing was rejected due to incorrect 2018 AGI, but 2018 AGI is correct

[lenni_lenape]

2019 tax filing was rejected due to "incorrect 2018 AGI".  But 2018 AGI is correct according to my pdf of my taxes from turbotax.  I assume the issue is that my 2018 taxes were filed, then rejected (b/c my now ex and I both tried to claim our kids, well, and she must have beaten me to file her taxes first last year).  

I filed my 2019 taxes before attempting to fix the 2018 ones (still haven't done the 2018 ones b/c I'd owe $, essentially the $2k she "stole" by claiming the child).  A related question is, "have I now not filed my 2018 taxes b/c of the rejection"?   

Suggestions on what to do and in what order?

Enter a 0 (zero) for the 2019 AGI and e-file your tax return again.
