I received the same thing when doing my 2025 Federal return. I signed onto the Federal IRS website to view my 2024 return and it hasn't been uploaded by the IRS yet. Guess the Federal workers are overworked. LOL.
I resolved the issue by making my AGI "0" and my efile was accepted. I believe the IRS website is where the validation is occurring so even though the AGI from last year is correct there is nothing to compare it to.
