".....IRS refused to accept it..."
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.
@ProudNDeed Are you having trouble with the Desktop program installed on your computer? Did you end up using the Online version?
You don't have to pay for the program again, unless you bought the Desktop program and then used the Online version. You can't apply the Desktop purchase to the Online version. If you did use the Online version you need to pay for Online and you can get a refund for the Desktop program.
I had trouble with my Desktop program and downloaded it again. The Download has all the updates to now. When you log into your online Account and go to Products & Billing all your years are listed. If you click on Licenses and Downloads you can download it again, even get the download for the other operating system Windows or Mac. Your tax data is in a separate file ending in .tax2024 and wasn't affected when I downloaded the program again and reinstalled it.
