By withholding I assume you mean taxes were paid in to a government taxing entity (IRS, Co or NY revenue departments) to your account, under your social security number. If so, you report that as estimated tax paid in TurboTax by using the following tabs:
- Federal
- Deductions and Credits
- See all tax breaks
- Estimates and Other Taxes Paid
There are options to report taxes paid to both federal and state taxing authorities in that section.
