cost basis for my long-term stock sale transactions reported to IRS in 1099 is based on FIFO method. Can I use a different method - specific identification of shares - for tax computation ? I'd like to change cost basis by using a different lot of shares that I bought at a higher price. Is that OK ? If so, do I have to do anything different in way of capturing this cost basis (shares bought at a higher price) in Form 8949 ?
