If i rent out a house but keep the garage as personal use would that be considered as renting only a portion of my rental house?

[AmandaR1]

Yes, that's correct. The rules define that any day of personal usage should be accounted; see "What is a day of personal use?" at the IRS rental publication  HERE.  

You can choose to let the software calculate your expenses, so that you only need to enter your expenses for the entire home.  The software can then calculate your rental expenses based on the square footage percentage of the home to the entire property (home + garage). Also, if you make these selections, the software will allocate the personal portion of property taxes to your itemized deductions and same with the mortgage interest (if it doesn't exceed the second home/1.1 million limitations). 

To enter this:

1. Click Take me to my return
2. Select the Federal Taxes tab and then click the Wages & Income tab below it 
3. Scroll down to the Rental Properties and Royalties section and click the blue hyperlink Show more
4. Click Start/Revisit next to Rental Properties and Royalties (Sch E)
5. Next you'll be asked about your real estate involvement and then you'll be at a summary screen of your rental property(ies) (or you can start setting up your rental). If already started setting it up, click Edit next to the property.
6. If you already setup your property, you'll be at Review your XYZ Rental Summary. From this screen, click Edit next to the Property Profile. On the screen titled, Do Any of These Situations Apply to This Property? be sure to select I rent out part of my home.  The next screen will recommend letting the software allocate your expenses and you'll need to select Yes to let the software do so. Continue answer the questions.
7. Back at the Review your XYZ Rental Summary you'll be able to enter all rental income and expenses, making the selections from this screen.

So when I answer "Percentage of time I used this item for this business in 2019" The percentage can apply to the percentage of the property is rental house and percentage property is personal garage? (80% rental 20% garage)

So when I answer "Percentage of time I used this item for this business in 2019"

No. As you work through the program you'll have two basic questions to deal with on percentages.

 - Percentage of property used for business (this will be LESS than 100%)

 - Percentage of time it was used for business (this will be ONE HUNDRED PERCENT)

One question is based on the percentage of the property used in the business. The other question is based on the percentage of ***TIME*** it was used for business.

so *PAY* *ATTENTION* *TO* *DETAIL*.  After seeing this screwed up by many in the past, I can't stress this enough.

I don't want to beat this to death but I found the place to enter the "Time" I used the property for business. I have not found the question about what percentage of the property was used for business. Can you help me locate it? I am using turbo tax premier desktop.
