It sounds like you were rejected for your AGI which is on line 11 of your 2024 Form 1040.
If it was rejected for AGI—-your 2024 AGI might not be in the IRS system if you filed late. Try using zero instead.
If filing with zero is rejected then file again but select the option that you did not file last year. The IRS does not see that question and it will allow you to e-file with no AGI question.

If that does not work and you still cannot e-file, then print, sign, and mail your tax return.
You have to access your own account and/or print it for yourself using exactly the same account and user ID that you used when you prepared the return.
