TurboTax not handling 3rd party Paid Family Leave correctly. How to fix?

My wife's company uses a 3rd party(LINCOLN LIFE ASSURANCE) to administer paid family leave (maternity leave, in her case). LINCOLN sent us a W-2 form with:

  • Box1 blank
  • PFL amount entered in Box12 using Code J
  • Box13 checked for Third-party sick pay

I entered the W-2 info in TurboTax and then selected the box to designate PFL as being included.  I expect that the PFL amount in Box12 needs to be taxed federally. However, adding this W-2 did not change my wife's income and had no impact on our federal return.  How can this issue be addressed? (I wish I could truly just skip paying the tax, but surely the feds will want this money)
