Where do I enter depreciation $ for IRS and CA? I'm a limited partner in a multi-apartment complex real estate SYNDICATION in AZ. And will this increase my refund?

The partnership enters depreciation on the partnership return and the amount is passed down to you on a Schedule K-1 which is what you put into your tax return.

Depreciation is subtracted from the partnership income. An overall net loss from the partnership may increase your refund.
