Thank you very much for your reply!
I looked through the worksheet and found that the $5 difference was caused by a $5 entry for expense of sale. An error as far as I can tell - not sure how it got there.
Regarding your comment "your vehicle should be completely depreciated", I calculated the depreciation number by looking up the annual miles over the years and used the per mile depreciation for each year provided in the table in Turbo Tax. As I mentioned initially, the standard rate was used in all but 5 years and I have no idea what depreciation may have been taken in those other years when actual expenses were used. The car wasn't listed on any of the depreciation schedules in my return and my CPA is no longer available to assist me. I assumed all was ok because it was a personal vehicle partially used for business.
If the sale is a taxable gain, so be it. It seems like Turbo Tax was using the business portion of the sale price as a gain and I was having trouble believing that.
