Deductions & credits

Well - I'm back on turbotax and the "Jump to" option is not visible/available.  So, I went to the section in Income for Home Sale and input the main home info and it is telling me I'm not eligible for the exemption.  Clearly I am. I am totally stumped and considering leaving turbotax for this tax year bc the deadline is looming and I need a system that will calculate this right.
