Rejected return - Spouse AGI

My 2021 electronically filed federal return is being consistently rejected by the IRS with error message that Spouse AGI for 2020 does not match prior year.  We file jointly every year.  I checked our 2020 return on IRS site and the AGI shown there matches what is shown in the TurboTax window that shows as prior year AGI. 

 

I see something in the error message referring to a "header".  Is it possible that the prior year AGI amount is not being properly included in this "header" when my return is transmitted to the IRS by TurboTax?  If this is not the case, is TurboTax in contact with the IRS to find resolution to this filing issue that, I suspect, is causing more than just my return to be rejected? 

 

When contacting Turbotax support, apparently, my only option is to change my filing method to paper and mail in my return.  I am not pleased about waiting for 6 weeks for my mailed-in return to be processed.
