From 1040 for 2016 (Long form) has the exact same lines on page 2 starting with lines 38, 39 1 & b, then lines 40 - 79. As near as I can tell, there is NO change in line numbers for the Federal Tax form 1040 in Turbo Tax. It is the same as 2015. Line 39a has a box with the number of "total boxes checked". Turbo tax automatically checks those boxes and adds the number that were checked. The first 2 boxes are for noting that the filer(s) were born before Jan 2, 1952.
