Kudos to AmeliesUncle who was right both times.
After much silence and an accountant's apology, I was told they should have used the HY convention (AmeliesUncle's point) and therefore the depreciation for the carpet is $3,575.
I made all the changes and everything looked right until I got to the summary page. Since there are three partners the numbers I entered were correctly divided by three. Turbotax gave me a co-owner share of income $25,522.76 and expenses of $30,815 which matched the accountant's numbers. Unfortunately, the 1/3 co-owner split of Assets/Depreciation ($18,990.14) isn't listed on the rental summary. Instead, it lists the full $56,970.42 for all three partners.
Why would Turbotax divide the other two items (Income and Expenses) correctly based on the building and land cost basis, but not divide the Assets/Depreciation figure by three? According to Turbotax, I have a Net Loss on property of $62,261 for which I can deduct $25,000. The accountant's spreadsheet has a Net Loss of $72,844.62 for all three with a co-owner share of $24,281.54.
