Form 1116 line 18 does not match 1040 line 15

Request your advice:

 

  1. Form 1116 line 18 says "Individuals: Enter the amount from line 15 of your Form 1040, 1040-SR, or 1040-NR."

But the value computed by TurboTax does not match the value in line 15 of form 1040. (I am normal salaried emplyee with RSUs/ESPPs and do not own Estates and trusts)
