After you file

You should be able to amend a second item in your California tax return. 

Here are some steps:

Important Note:

For California, you must file your refund claim by the later of:

• 1 year from the date of overpayment
• 4 years after the original return due date (if you filed before the due date, after the extension, or made payments and never filed a return)
• 4 years after the date of a timely filed return, if filed within the extension period

Steps to amend a second time (alternate steps below - if steps 1-3 d not work)

1. Be sure you are signed in for the link  in Step 2 to work.  
2. Go to the Amend screen.
3. Select Amend (change) return, then Amend using TurboTax Online.

4. On the screen OK, let's get a kickstart on your 2024 amended return, select The IRS or state sent me a notice (this will allow you to amend only your state return without making changes to your federal) and Continue.
5. On the next screen, select Something else and Continue.
6. On the screen Tell us which 2024 return(s) you want to amend, select 2024 state.
7. Continue until the Let's work on your state taxes screen. Select Amend next to your state return, and continue through the screens to make your amendments.
8. By the time you get to the Important: Read and Follow Your California Amend Instructions screen in TurboTax, we’ve already transferred info from your federal 1040X to your California amended return.
9. Move through the following screens to review your info and make any needed changes.
10. On the Confirm Previous Refund or Tax Paid screen, review the amount(s) provided and update if necessary, then Continue.
11. On the About Your California Amended Return screen, you’ll see the form for your amended return.
    • Scroll through and review your info.
    • Answer any questions that may still need to be answered.
    • Select Continue.
12. On the Let's Make Sure You're Ready to Review screen, choose Yes, I’ve entered everything and let’s review, and Continue.
    • If you have additional info to enter, choose No, I still have state amend info to enter and move through the screens.
13. At this point, we'll check your California amended return for any info that needs to be reviewed. If we find something, select Fix Return on the Let's make sure everything is accurate screen and update the requested info.
    • If you then see an option to Run Smart Check, run it again to ensure you didn’t miss any info.
14. Follow the onscreen instructions to finish and file your return.
