I clicked on the warning and it brought me to the correct location in Turbo Tax, but when I went to find it again, I couldn't. The item is a farm tool and I was given the opportunity to adjust the CCA up to the value of the piece of equipment.
In TurboTax Online Self-Employed, go to Income > Self-Employment, then select Edit beside your business. Click continue until you reach a list of checkboxes, and check off Calculation of CCA Claim, then press Continue. This should bring you back to the page where you can adjust your CCA claim.
