Do i enter annual home office expenses or just a portion of it on Turbotax online?

[amarisred]

I have home office expenses from my self-employed job. How should I enter that into Turbotax online? The software asked me to provide "total amount for expenses." 

Does that mean I put the total cost of rent, internet and utilities for the 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?

Thank you

You would enter the total amount of the expense, and then TurboTax will calculate your allowable portion based on the information about your workspace that you gave earlier.
