How to deduct home office on for 8829

[Pzoo]

TT is asking me to review the entry for my home office deduction. The asset is the actual home office, but it's asking me to "enter the total cost when asset was acquired". Do I enter the total cost of the house and expect TT to go back in and take 13% of that number (the office is 13% of the total house square footage), or do I take 13% of the total house cost and enter that instead?

Yes, you enter the total cost of the house and TurboTax will apply the 13% to that number automatically.
