About 8949. I previewed my tax return and on 8949 both my wife and I are named but only my social security number is showing. The accounts are hers. Can turbotax specify

Form 8949 shows the Social Security Number of the first named person on the Form 1040 when a couple files as married, joint.  Accordingly all the security trades reported on the various Form 8949's will show the same Social Security Number as that's how the IRS tracks the information.  TurboTax has no facility to somehow declare "these trades belong to Spouse 1 or Spouse 2.
