I e-filed my Colorado State Taxes with Tubo Tax for the 2022 tax season. My total charitable contributions subtraction was greater than $5,000, so I understand I am to submit documentation confirming my contributions, but turbo tax did not provide any way for me to attach the documentation to my e-filing. How do i submit this documentation?
At the screen Tell Us How You Will Submit Documentation under the Colorado state income tax return, you see three options.
