apparently Turbotax is hacked? they are saying my returns are rejected

Why do you think that means TurboTax was hacked?

You received an email that we cannot see that tells you why your tax return was rejected.  

Some rejected returns can be fixed and re-filed.  Some have “un-fixable” reasons for the rejection and have to be mailed instead.

 What is the rejection code or rejection message? 

 If it was rejected for AGI—-your 2023 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.
