@DianeW777 If you re-read what you quote from the IRS, it does say this at the end: "If you have to add two or more amounts to figure the amount to enter on a line, include cents when adding and only round off the total."
IRS clearly says to include cents when adding and only round off total to figure the amount to enter on a line. Following this, all Proceeds for each line should be added with cents to get the total then round off, same for Cost Basis and Gain/Loss. TurboTax program is currently rounding Proceed and Cost Basis first then computing the total and Gain/Loss - which is not correct following IRS instruction and creating huge difference.
