My e-file has been rejected now 5 times.

I have TurboTax Deluxe. I have completed and e-filed my 2020 tax return. It has been rejected now 5 times. I have verified my AGI with my 2019 tax return and even logged in to the IRS website and verified the number is correct.

I have filed my mail for the previous 7 years but want to file electronically this year.

I have verified all info correct   and have filed jointly with my wife.

What else can I try to get this returned filed electronically? I am stumped...
