Do i enter overall home office expenses or just a portion due to size of office?

For home office expenses such as rent, internet, cell phone - Do i enter overall cost or just the portion i believe was used for work?

Are you employed or self-employed? Are you using TurboTax CD/Download or TurboTax Online?

I have a similar question. I have home office expenses from my self-employed job. Do I put the total cost of rent, internet and utilities of entire year in the section? Will turbotax calculate the percentage usage automatically? Or do I need to calculate the percentage usage manually and put that number in home office expenses?

Thanks
