Thanks @VolvoGirl! This makes sense now.
In case it's helpful for anyone else this is the path forward that I'm taking:
- You can e-file amendments for Colorado here: https://www.colorado.gov/revenueonline
- You're able to see your forms in the TurboTax software (there's an option on the top right side to see them), so I'm using the state forms from this view since I'm unable to print them out.
