I bought a computer in the tax year period. In Personal > Deductions & Credits, I am asked if I bought or own computers ... used to manage my investments. I use the computer, in part, to manage my investments, but I use it for many other things (I don't write it off for any business purposes). I looked at the help file, but it didn't answer my question, which is: can I write off the cost of this computer for managing my investments? I highly doubt it, given that is not its main purposes, but based on the way the question was phrased, I thought I'd ask. thanks
