I completed a 1040X via Turbo Tax for my 2015 tax return. When I printed the form at the end, there are all zero (0) amounts listed under "A. Original amount or as previously adjusted" column Lines 1-15. My reason for filing a 1040X is to add deductions and credits not previously filed on my original 2015 tax return. The addition of the deductions and credits will create a larger refund due. I received a refund in 2015 but the 1040X put a value of zero (0) in Line 16 also. Since I filed my original 2015 taxes with Turbo Tax and completed the 1040X amendment through Turbo Tax, shouldn't it have pulled those values in on the 1040X? Thanks.
