I called Colorado Dept of Revenue today and was told I can use their online system to file my return and use the eFiler to upload the additional DR 0617. But I'm not sure how that works or if it will significantly delay processing of my refund. Submitting via paper and snail mail will take ~12 weeks to process. Not having this ability in TurboTax directly kinda defeats its usefulness.
FYI and IMHO: Soon everyone will be buying EVs for the whole family
