Computer Deduction

Last year, I claimed a full computer on my sch c for ebay sales. I purchased it in November and put it to use in December, the total deduction was 656.00. Well I only used it in December and got a tablet from work in January which I now use. I gave the computer to my son. I need to pay money back now I believe? Will turbo tax automatically do this for me and take the amount from my refund. If so, how do I complete this? I complete a sch c for ebay along with my 1040
