After you file

As @xmasbaby0 said, you cannot do anything until the governing entity approves your return - in your case, this is Colorado, not the IRS.  Colorado is currently having program issues so they will not begin accepting state returns until 02/22/2023.  

After that date, and once your return has been approved, you can log in to TurboTax and follow these steps to amend your state return:

1. Sign in to TurboTax
2. On the home screen, scroll down to Your tax returns & documents and select the year you want to amend
3. Select Amend (change) return, then Amend using TurboTax Online
   • If you're told to amend your return via TurboTax Desktop, follow the steps for TurboTax CD/Download below instead
4. On the screen OK, let's get a kickstart on your 2022 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 2022 return(s) you want to amend, select 2022 state
7. Continue until the Let's Amend your State Taxes screen. Select Amend next to your state return, and continue through the screens to make your amendments
