My 1099B has 2 total lines for Long Term Capital Gains: NET Long Term Capital Gains and losses, and SALES PROCEEDS AND NET GAINS AND LOSSES. Which do I enter in TurboTax?

Both have boxes 1a-1g but they are different amounts on each line. Turbotax doesn't clarify which to line to enter just "Sales total."

You need to enter proceeds and cost basis for investment sales. I'm not sure how that is listed on your Form 1099-B, but the sales proceeds less the cost basis would give you the net gain on sale. Those are the amounts you need to enter in TurboTax.
