I received an IRS refund for 2017 taxes, but the IRS informed me my refund was overstated and had to pay back $1077. WHERE does this tax credit go on the 2018 return?

I paid back $1077 to the IRS based on an overstated 2017 refund, and believe I can claim this repaid tax on my 2018 return.   But I can not find WHERE this tax credit goes.   Turbo tax suggested I put it under Estimated Taxes, but I want to be sure that is right.
