Your scenario did not work out right.  Please follow the blue links for more information.  I recommend looking at the actual Schedule E form and instructions. The Sch E should be reporting your expected income and your expected expenses. The allowable expenses will be reduced with your personal days. Personal days do not include days where you are doing work, upkeep. maintenance.

The best source of information is the IRS. They have a news article on rentals. They also have a full publication of everything you would want to know.

Thanks for the reply! I actually did what you suggested before asking my question.  I not only read that material and the Schedule E instructions, but also and IRS Topic 415 Renting Residential and Vacation Property).  I also used the actual form itself as well as the TT Worksheet.  The only thing I did differently was change the number of personal days from 50 to 5.  And as I said, the Schedule E (2018) with 50 days of personal use reduced my taxes by $1,600 and the Schedule E with 5 days personal use did not give me any reduction or increase.  Again, that seems backwards since the 50 days personal use resulted in proration of expenses.  As for TT 2019, changing the number of personal days did not change alter my tax in any way.  I appreciate your thoughts and time.  Thanks!
