Deductions & credits

Thank you this is helpful, but i think i found a bug in turbotax, after doing what you mentioned above and transmitting my return my fed & ca returns were rejected as there were some form updates done on turbotax on 28th, so i downloaded that and went through the process again and now it wont even "Efile" my california returns.

The reason is that ,  lets say i had  15,000 as mortgage interest reported in deductions and credit section of turbotax , out of which 4,000 shows up with my primary mortgage lender that i stayed for 2 months in the year and since the other home became rental 11,000 was the portion of time when i lived there as my primary home(but that doesn't show up as lender and flows automatically to calculate the 15k =11k+4k)

So on the "Miscellaneous Itemized deduction statement", its asking me to enter -11k(mortgage interest adjustment) when it should be 0 because turbotax is thinking that i had only one lender whereas i had two.

Due to this i am unable to E-file my state return as it says there is an error , can you please help?
