Mixed use of house - allocation of interest and taxes

I use my house as my main residence but i also rent out two of the bedrooms.(dedicated to rent, no personal use)

I entered ALL interest and also ALL taxes into the schedule E section that asked for it. I chose vacation home for the house since i use it as personal and also rental. I was expecting some sort of proration to happen automatically by turbotax that carries the prorated tax and interest into my schedule A, which does not seem to be happening properly, i do see some interest and tax moved there but it does not add up and i cannot figure out how it is adding those values. I thought its based on the business use percentage i gave it in the depreciation section of the rental but it is not exactly prorated based on that it seems like. i thought i would prorate it myself between rental and personal. its quite a mess. any ideas?
