I bought options on 4 lots of 50 shares each on 4 different dates in the same year (2013). They expired worthless in 2018. According to TurboTax, a contract is 100 shares. I tried entering 0.5 in the # of Contracts box, but it rounds up to 1 for each of the 4 lots. How can I resolve this and enter it correctly in Turbotax? Also, the math is slightly off to calculate the total loss
