I just saw that Turbotax lets you mix entries of a summary for Box A grouped together (where there are no special exceptions, like values in 1g), another summary for Box D grouped together (again, where 1g and other special fields are 0), then individually each sale that does have special exceptions (like 1g not equal to 0). So I filtered each of those summaries and cases in a spreadsheet to compute the totals for each of those summaries. Because the vast majority of the entries had 1g = 0, I only had to enter 2 summaries + 8 individual entries (where 1g is not 0) instead of the hundreds of entries.
It looks like you can instead choose to ONLY enter two summaries, but then you also have to mail in a printout of the 1099 forms because of those special exceptions (like 1g) that you chose not to include in Turbotax.
