Investors & landlords

Hello..

I see line 21. is correctly showing..

here is the screen shot. I already paid turbo tax and filed...

but Still wondering why my return is so low.

while I was inputing by turbo tax...I didn't saw any part letting me put my CA car registration, donations etc.  If I put those will my tax return increase?..  I don't know why turbo tax skipped me those for me to enter. thanks.
