I think Turbo tax made an error on my 2016 tax form 4562 by depreciating the wrong value for my rental property for the first 8 months in service, what should I do?

[xqpmm15]

 The cost of the house, net of land, is 117,267, placed in service May 2016.  Using GDS and 27.5 year depreciation the tables show to use 2.273% .

This would equate to $2665.

Turbo tax calculated $1786.  They added to the equation the cost of the house to be 67% of the total value. 

That would be a double whammy  - the tables show the reduction by having the year 1 table.  There shouldn't be two reductions.  

As shown in Pub 547 pg 11, I believe this confirms my statements above; 

Example. You purchased a single family rental house for $185,000 and placed it in service on February 8. The sales contract showed that the building cost $160,000 and the land cost $25,000. Your basis for depreciation is its original cost, $160,000. This is the first year of service for your residential rental property and
you decide to use GDS which has a recovery period of 27.5 years. Using Table 2-2d, you find
that the percentage for property placed in service in February of Year 1 is 3.182%. That year's depreciation deduction is $5,091 ($160,000 x 0.03182).

Can anyone help me out please?

Several things you need to check on your end. Elect to edit the asset.

Third screen in is "Tell us about this rental asset" 

     The "COST" minus "COST OF LAND" should equals $117,267.

     Date purchased or acquired will be May 1st, 2016 or earlier (before that date) This date does not matter for depreciation purposes at all.

Next screen, "Tell us more about this rental asset"

     Select that you purchased it new, and also select used 100% of the time for business. You select 100% because after your "in service" date it was *IN FACT* used 100% for business. What you used it for prior to the in service date just flat out does not matter.

     The in service date I used was 5/1/2016 but any date prior to 5/20/2016 gives the same exact results in the end. (as it should).

Next screen, "Asset Summary"

     Shows 1st year depreciation of $2,665 - spot on the money.

So walk me through what you did so I can duplicate it to get the same wrong results as you did.
