My net sales price from employee stocks is in 1d of my 1099B. Turbotax calculates this for my cap gains sheet, but it is $.01 off due to rounding. How can I fix this?

You don't.  The IRS only cares about whole dollar amounts.

Thanks! a Turbotax professional did also confirm that they round down, so it was OK to just change my box 1d in the capital gains worksheet to what Turbotax calculated.Thanks Zbucklyo!
