You will have to report it on line 36 of your Schedule 1(Line 22 for 2019). This usually flows from Form 8903, but TurboTax does not support Form 8903. So here what you will need to do:
1) Use TurboTax Desktop (TTD) version, not TurboTax Online.
2) Use this form to fill it out manually https://www.irs.gov/pub/irs-pdf/f8903.pdf
3) Then open your tax file in TTD and go to Forms - top left corner for Mac users and top right corner for Win users.
4) On the left where all the forms are listed, find 1040 Wks.
5) Scroll down to line 36 and right above it, you will see a Worksheet.
6) Add DPAD description in line H.
7) Put the amount from line 25 of your Form 8903 (see step 2).
😎 Enter the amount.
You will have to file by paper since Form 8903 must be attached to your return and it is not part of TurboTax.
