Pls confirm I will need to prorate manually
It depends on if you elected to do so manually, or if you elected to let the program do the splits for you. I suggest you elect the option to do it manually. When you let the program do it for you, it does not split everything and you are still required to split some things manually.
The main one is property insurance. For the period of time it was your residence, property insurance is not deductible anywhere on the tax return. For the period of time it was classified as a rental, a pro-rated portion of the property insurance is deductible on the SCH E line 9. If you elect to let the program do the splits for you, the insurance will not be split or pro-rated. It will apply whatever amount you actually enter.
Take note on the insurance that the IRS treats all of this "AS IF" the period of coverage is from 1 Jan - 31 Dec of the tax year. What the actual coverage period is just flat out does not matter. So if you paid property insurance on June of 2021 and the coverage period is Jul 1 2021 to Jun 31 2022, you will pro-rate "AS IF" the coverage period is 1 Jan - 31 Dec of the tax year.
The same holds true for your property taxes too.
I also highly recommend you check the figures for depreciation in the Assets/Depreciation section and confirm they are right. To do that, see IRS Publication https://www.irs.gov/pub/irs-pdf/p946.pdf and use the worksheet that starts on page 37. For line 6 of the worksheet, table A-6 on page 72 applies.
Because of IRS rounding, what you figure manually and what the program figures may be off by a few bucks. That's perfectly fine.
Like I said before, perfection in your first year is not an option; it's an absolute must. So if you have questions, no matter how dumb you may thing they are, please ask.
