Solved
I've been filing through Turbotax Online since 2013, but the computer I had my 2015 and 2016 tax returns on croaked and I don't have them backed up. I only had my business mileage documented on the returns for those years, so I'm having trouble calculating depreciating for a sold vehicle now without that data.
