No, the payments you have been making are not deductible and do not get entered on your 2019 return. The IRS already knows about your payments. If you still owe, and your 2019 return shows a refund, the IRS will take your refund up to the amount you still owe.

NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.
