Turbo tax Delux program error

My 2019 return was rejected because LAST YEARS AGI entry didn't match the government records. I wasn't asked that question on the return and if it was missing why was I able to continue and pass the review and file prior to filing.

I wasn't able to get the answer to the question after being on the phone with two different specialists for 55 minutes!

I would appreciate an answer to this question.
