Schedule E

We have a rental that we rent out and also have personal use over 14 days. When completing Schedule E, I figured out 87% of the expenses were for rental and 13% were for personal. When entering my expenses I only entered the 87% amounts. My expenses entered were more than the rental income so was not able to deduct all the total expenses. I thought the unclaimed expenses were to be carried over to next year, but I never saw a carryover amount or worksheet stating that. I just now found a worksheet that showed the difference was allocated to personal use.  Not sure why they are allocating expenses to personal use as I already had subtracted 13% of expenses before entering my info.   Can you tell me was I suppose to enter 87% of the expenses or was I suppose to enter 100% and turbo tax would divide them between rental and personal? Is there a carryover of expenses not deducted?  Thank you for any help you can give me!
