Thank you for your reply. I've done that, and it is still unsuccesful.
For further reference, I've finished my vehicle deductions, but the online platform does not prompt me to enter my UCC for 2023, or does not grab it from 2022. Additionally, it still prompts me to "start" my vehicle expenses on the list of self-employment expenses page, even after I have entered all of my deductions and have finished that section. I do believe there is a bug in the system.
