When providing multiple 1099-B provided by different brokers like Robinhood or Schwab, etc, is long term and short term capital gains calculated across all brokerages?
Say one is using FIFO (First In, First Out). That person sells 10 shares of ABC stock on 11/10/2021 with Robinhood which they bought on 6/10/2021 but they also bought 10 shares of ABC stock on Schwab back on 5/5/2020. Does TurboTax reference the 10 older shares on Schwab as its basis for tax purposes?
If only referencing Robinhood, this would show as a short term gain.
If referencing across all brokerages, this would show as a long term gain.
