I efiled using Turbo tax. But Turbo tax says I didn't what is wrong?

Here's how you can fix it: 

Sign in to your account and select the Fix my return button. Follow any “fix it” instructions to update the information causing the rejection. 

Note: Not all rejections will have explicit guides to fix the information. You’ll need to navigate to the program area to address the cause of the rejection. 

Time-saving Tip: If what you originally entered is correct, you won't be able to e-file. There's probably a data mismatch at the government, a dependent that's already been claimed, or some other situation beyond your control that prevents your return from being e-filed. In this case, your only option would be to print and mail in your return. This article will give you instruction on how to print and mail your return.

The IRS uses your prior year AGI to combat fraud.   

You can find your 2023 Adjusted Gross Income (AGI) by:

• Looking at line 11 on page 1 of your 2023 Form 1040
• Requesting a transcript of your 2023 tax return from the IRS. You can request your transcript online at the following link: Get Transcript 

Please click on this TurboTax article for more information. 

Check these items as well to ensure you have the correct number.  If you: 

• Filed late last year after mid-November or your return was processed after that time—try entering 0. 
• Amended your return last year—make sure you’re using the AGI from your original return, not the amended one. (If you only have a 1040X form, it’s on line 1, column A). 
• Rounded your AGI to the nearest dollar—be sure to round up when it’s 50 cents or more and down when it’s 49 cents or less. 
• Filed with your spouse last year—you and your spouse have the same 2023 AGI. (Don’t split the AGI amount or enter  0  for one of you). 

Time-saving Tip: If what you entered is correct and you continue to get a reject, you won't be able to e-file. There's probably a data mismatch at the government, or some other situation beyond your control that prevents your return from being e-filed. In this case, your only option would be to print and mail in your return.
