2019 return Rejected, AGAIN for the 8th time

I have not been able to file my return because it keeps getting rejected.  It is always for the same reason, the AGI is incorrect.  IT IS NOT INCORRECT, it is the same as on last year's return and it is the same as shown in my account on-line at IRS.  I am going to have a penalty for this, even though I filed by the filing deadline and it was rejected.  It has been rejected 7-8 times since then, always with the same reason.  I have reviewed my return a dozen times with no mistakes found.  I have even started over, doing the return again from beginning to end (which is a minimum 2 day job for me) and it was rejected again with the same reason, incorrect AGI.  I am going to have a penalty, even though I filed on time.  Is there anyone that help with this.  I do not want to send a paper return because I sent a paper return last year and I think this is what is causing this problem now.  If it can't be fixed now, does this mean I will have to sent a paper return from now on.  I don't like that, I want this corrected so I can e-file.  Can someone help with this, please.
