Return being rejected because of AGI, but I filed 1040X

I've had my 2019 return be rejected twice now claiming the AGI is incorrect. I filed a 1040X last year and I have verified several times that my AGI is correct. I checked the IRS site to verify they confirmed my changes in my 1040X for 2018.

 

However, I'm wondering if the issue (that I still have to call the IRS about, but it's currently the weekend/about to be a holiday...) is that I never got my amended refund after it was completed last year and I believe that's supposed to be taxable if interest on the refund was accrued (which I assume some has since it's been a year and I haven't gotten my full return).

 

Is this the likely issue or am I missing something here?
