You have the choice of allowing TurboTax to do the allocating or choosing to do it yourself. Personally, I like to do it myself, but that's just me.
When you're answer
the question regarding how many days is a room in your house rented, answer the
number of days rented (258) and how many days you
used that room personally the rest of the year (107). You can't rent it
and use it personally at the same time.
Here's some other
info you may find helpful:
"Do any of
These Situations apply to This Property"
Select "I rent
out part of my home".
When you marked the
box for TurboTax to allocate per the percentage of the business portion of a
mixed-use property the expenses are only entered one time in the rental section
and TurboTax will allocate correctly to personal Schedule A and business to Schedule
E according to the percent you entered.
Yes, to let TurboTax
calculate the expenses for you.
On screen
"enter use percentage" this where the % goes for TurboTax to do the
calculation.
Enter rental use
percentage.
TurboTax will flow
personal to Schedule A and rental to Schedule E.
Only the exclusive
used are is considered rental area.
Common area is
available to all and is not a factor in allocation of expenses.
How to divide expenses. If an expense is
for both rental use and personal use, such as mortgage interest or heat for the
entire house, you must divide the expense between rental use and personal
use. You can use any reasonable method for dividing the expense. It may
be reasonable to divide the cost of some items (for example, water) based
on the number of people using them. The two most common methods for
dividing an expense are (1) the number of rooms in your home, and (2) the
square footage of your home.
