Can I claim both cell phone and land line as home based non incorporated business expense

Absolutely, yes, if both are used for business purposes.

Thank you for the answer but could you tell me exactly where to enter the cell phone portion on Turbo Tax.

Turbo Tax also didn't guide you to where you enter your home and internet expenses. I entered it under other expenses in part B. Because its part of the home I only get the portion I use for the business. The cell phone is completely different and what percentage is allowable for that?

That was home phone and internet expenses.
