You personally don't figure anything. The convention used in that first year is based on the in-service date of the property or asset. The program takes care of that automatically and it does so correctly.
TurboTax calculates $0 for depreciation,
That's probably because you indicated you have personal days used greater than zero, when days of personal use should be ZERO. Additionally, business use percentage would be 100% (one hundred percent) with zero days of personal use.
This is what my accountant wrote to me (he had been doing my taxes for years).
"Your rental was set up with a 31.5 year straight-line recovery period using the mid-month MACRS method. Your software should have these options. 2019 is year 30, and the depreciation expense for 2019 should be $1541 (48,532/31.5). Depreciation deducted in prior years (1990-2018) was $44,103."
However, I can't find out how to do that in TurboTax. I have ALWAYS had it rented. I have never used it personally -- bought it for rental.
do you know how and where to enter rental info? in that worksheet, there is a link for asset entry. that's where you enter the info about the property as to date acquired, date placed in service, cost type of property and life. then look at the history section to see if it matches what your acct said and that depreciation matches. by default, a mid-month computation is done on real property. really only affects 1st and final year.
I found where I enter the amount I have depreciated in prior years, but when I entered the correct amount, it still tells me that I get $0 depreciation, and that I only have 27.5 years to fully depreciate. It shows this:
