Since you're using Premier online, I'll assume you are trying to take a deduction for a home office for W-2 work. That deduction is no longer allowed under the new tax laws.
Here's how to reach TurboTax Customer Support, as long as you have PLUS or higher. Regular Free Edition does not have phone support, so if you are using Free Edition, you can get help in the forum, or we can tell you how to contact a Support agent at Facebook or Twitter.
Hours are 5AM-5PM Pacific (8AM-8PM Eastern) Monday-Friday.
