If my amended 2019 return is still awaiting approval due to covid-19, should I use my 2018 for reference to AGI?

The IRS rejected my 2020 return saying my spouse's AGI doesn't match the 2019 which of course hasn't been accepted yet since I had to file by mail due to a silly mistake on my part.  So should I use the last confirmed AGI which would be from 2018?
