Get your taxes done using TurboTax

I need help on the desktop version here is my example. I am paying back Social Security Disability (this is from 2018) I received the 1099 which shows the total amount as a negative. I want to claim the right for repayment in the forms section. I entered in the total amount of payment (3,001) is this correct? Or am I to enter in the tax paid? If so, how do I calculate the tax from that specific tax year? Do I also enter in the 1099 negative number when i am entering in ths right to repayment section?
