i RENTED MY TIMESHARE FOR 7 DAYS AND RECEIVED A 1099K. IS REVENUE TAXABLE? HOW DO I REPORT IT? THOUGHT IRS ALLOWED UP TO 14 DAYS WITHOUT MAKING RENT TAXABLE

No, it's not taxable.  But, you will need to enter the 1099-K information since it was issued to you and the IRS.  After you enter the 1099-K, you can indicate the income shouldn't be taxable.  See: 14 day rental rule. 

To enter the 1099-K:

1. Navigate to Federal > Wages & Income > Other Common Income > Form 1099-K
2. Enter the information from the 1099-K
3. Check the box that says This amount in box 1a is too high or includes some personal transactions
4. Enter the amount that shouldn't be included, which is the entire amount
