Why is vehicle expense information not transferring?

2025 TurboTax Premier is not transferring vehicle information and depreciation from the previous year. I started putting the information in manually but soon was asked questions I wasn't sure of like total depreciation. I have copies of my returns from those years so I know special depreciation was used the first year but no clue how to calculate what number to put on total depreciation. Please advise. Hopefully someone will tell me that an update will take care of this.
