There is no way to know how much you owe on one form of income. All your income gets added together. Look at your tax amount before and after entering the income to see how much you are taxed on the income.
The IRS says that if you rent out your house for 14 days or fewer during the year, you don't have to report the rental income on your tax return.
However, that rule would treat your timeshare as a vacation home only if you personally use it for at least 15 days during the year in addition to the days it is rented.
If you don't meet both 15-day rules, the income is taxable. This means that you must own a timeshare a minimum of three weeks at a single resort, with at least 15 days used personally.
This will be reported in TurboTax as Rental Income on Schedule E. Deductions allowed include annual maintenance fee, advertising, rental commission, depreciation, property taxes (if you pay them separately from the maintenance fees) and interest on your timeshare.
