1099-B filing separately

Hello I would like to confirm my understanding for a 1099-B where I want to split capital gains/losses 50/50 with my spouse:

 

  1. TurboTax does not give me an option to enter the full amounts and do an adjustment to reduce capital gains or losses to half in my own tax return
  2. Consequently, I should only enter half the amounts in my own tax return (entering the full amounts would exaggerate my gains or losses)
  3. I should also file a 1099-B to the IRS (and provide it to my spouse) for the other half of the amounts
  4. My spouse will enter her half in her tax return using the 1099-B I provided her

Is my understanding correct?
