Thanks for your reply.
I (single parent) did what you suggested, adding a dependent (student) who is over 18, that made only 8,060 in that year, less than the 10,822. After completing the choices, and choosing to claim the dependent by me, the family head, I thought I would see the difference of about 2,700 shown in line 305. I re-entered everything, and still no luck with anything in 305 of my return. As a test, I downloaded the free StudioTax and entered the same data, and it showed 2758.81 in line 305 of my return. It seems a lot more complicated, showing all the forms, and a little more clunky interface than your program, but it seems to handle the dependent calculation as expected. Any other thoughts on what I could try? Thanks for your help. If I can not figure this out, I think I will just file by paper reports.
